在设置有了诱杀装置的网页上，这个漏洞将允许黑客取得对未受保护的计算机的控制。对此，微软已经作出更新并优化了内存管理，但安全研究人员发现，这些保护机制在一些比较陈旧的Windows上无法使用。

“作为漏洞，这种是最严重的，因为它允许远程执行代码”，趋势科技资深安全分析师Rik Ferguson说，“这意味着攻击者可以直接在受害者的计算机运行恶意程序。”他补充说，“这让人想起，两年前的同一时间，漏洞曾促使一些国家政府警告不要使用IE浏览器，切换到另一种浏览器。”

浏览器安全是2010年一直在讨论的一个热点。在IE浏览器频频爆出安全漏洞的同时，各家使用IE内核的第三方浏览器的安全问题，也不得不让用户感到担忧。用户是否会因为惧怕IE安全漏洞而转投其他非IE内核浏览器的怀抱，值得我们继续关注。

作为开源领域的中坚力量，Mozilla一直努力致力于提高Firefox火狐浏览器的安全技术和保障用户的隐私安全。它采用Google Safe Browsing for Firefox技术，主要拦截钓鱼网站和恶意万展，保护用户免受病毒、蠕虫、木马和恶意软件的侵害。Firefox每天会获得关于伪造站点的更新48次，当用户访问一个伪造站点试图伪装（比如银行网站或淘宝网店）的时候，会有全屏的警告信息提示出现。同时，地址栏会变红，引起用户的注意，中止用户的进一步操作。

此外，Firefox火狐浏览器还提供了密码管理器、隐私浏览模式等一系列安全措施，帮助用户更安全的畅游互联网。

前不久，Mozilla发布了关于Adblock Plus扩展突破一亿次的新闻。近日，Mozilla再次公布了不同地区的最受欢迎扩展，美国和中国用户对扩展的喜好有着很大差异。

据Mozilla最新统计，美国地区最受欢迎的5款扩展依此为：

Adblock Plus

Video DownloadHelper

Personas Plus

Greasemonkey

Download Statusbar

而中国地区最受欢迎的5款扩展为：

Xunlei Extension

FlashGot

Adblock Plus

Firebug

IE Tab Plus

从上述排名可以看出，用户对火狐扩展的喜爱程度和使用目的有着很大差异。除了进行广告过滤的Adblock Plus外，其他最受欢迎扩展都各不相同。下载类扩展在中国很受欢迎，迅雷下载扩展和FlashGot都出现在本次榜单中。

由于受到中国很多网站网页不标准、网银支付只支持IE等因素影响，IE Tab Plus榜上有名，成为中国火狐用户网上畅游必不可少的扩展之一。此外，Firebug强势出现在中国地区榜单上，再一次充分说明中国有很大一部分网页开发人员都在使用Firefox。

为了给这些的Firefox 扩展用户们带来更好的使用体验，在Firefox 4.0中，扩展管理器（Add-on Manager）将会呈现一个全新的设计，这里为广大用户汇总一些新的特点：

1． Firefox 4.0中，扩展将会自动更新。目前的Firefox 3.6中，扩展的更新是采用提示形式，需要用户选择并手动进行更新。

2． 4.0版本中，扩展的更改将不再需要重启Firefox。这一点相信会让很多用户觉得惬意。

3． 扩展管理器将变成一个标签页，而不再是一个窗口，看下对比图：（左图是现在的扩展管理器，右图是4.0下的扩展管理器）

4． 多扩展的搜索做了优化，帮助用户更快捷的找到需要的扩展。

此外，全新的Firefox 4.0扩展管理器将会带来更快的启动速度，未来更会加入扩展功能提醒等更加人性化的功能和设计，帮助用户更好的管理和使用火狐的扩展。

本次浏览器硬件图形加速测试旨在横向考量现在浏览器对新的互联网应用的处理能力。

本次测试的平台选择在小编的一个普通的家用台式机上进行，配置普通，能够比较客观的反应浏览器的一个真实性能，由于硬件加速需要DX10的支持，所以需要选择支持DX10的显卡和windows vista以上的操作系统。测试机CPU:AMD 7750 内存：2GB 显卡：ATI HD4850

操作系统：选择windows 7 X64 旗舰版。目前cpu均支持64位操作系统，在64操作系统下，64位程序，相对于32程序性能有很大提升。

浏览器：由于除IE外 firefox和chrome均暂时没有原生64位版，所以均采用32位最新测试版：

IE 9beta版（64位版）

Firefox 4.0 beta 7

Chrome 9.0.587.0

本次测试中所有浏览器均使用默认配置，Firefox与Chrome均不安装扩展运行，所有浏览器均打开硬件加速选项。（Firefox与IE在选项设置中开启，chrome在 chrome:flags中开启）

测试页面选用IE9官方测试demo之一的微软beta鱼测试：http://ie.microsoft.com/testdrive/Performance/FishIETank/。该页面能够比较客观公正的反应浏览器的硬件加速能力。

测试方法：打开网页，beta鱼数选择1000条，全屏最大化运行1分钟，等帧数稳定后，取平均值，帧数越高性能越好。

IE9 Beta

Firefox4.0 Beta 7:

Chrome9.0.587.0:

测试成绩：

IE9 beta：37fps

Firefox4.0 beta7：44fps

Chrome9.0.587.0：42fps

在未开启硬件加速的情况下，三大浏览器均只有个位数帧数的表现，开启硬件加速之后，性能有了质的飞跃。总体来说，三大浏览器的表现，差别不是很大。但是，在微软自己官方的测试demo中，IE9的垫底表现着实让人感到意外。Firefox4.0 beta7在本次测试中表现惊艳，超越了有浏览器跑分王之称的Chrome。从beta6到beta7，Firefox 4.0搭载了全新的JägerMonkey javascript引擎，性能有了显著提高，期待Firefox 4.0正式版能给我们带来更多惊喜。

延伸阅读：beta鱼的来历：
beta 鱼是一种特殊的暹逻斗鱼(泰国斗鱼)，英文原名Siamese Fighting Fish，又称Betta Fish，而Betta的发音和Beta非常近似。微软在Windows7 beta版中默认的壁纸就是beta鱼，正式版去掉了，后来beta鱼就成了微软测试版的一个代号。

Under the terms of its anti-trust settlement with the European Commission, Microsoft will no longer be able to restrict choice toWindows users across the EU, as well as Iceland, Lichtenstein and Norway. Instead, it must help them make a choice: yes, they might retain Internet Explorer as their gateway to the web – but they will also be offered the options of Safari, Chrome, Firefox,Opera,AOL, Maxthon, K-Meleon, Flock,Avant Browser, Sleipnir and Slim Browser.

The screen – as well as a web page at browserchoice.eu hosted by Microsoft –is designed to display, in random order,
the icons of the five leading browsers by market share: Internet Explorer, Firefox, Safari, Opera and Google’s Chrome. The logos appear alongside some brief text about each; scroll accross and you will see less prominent mentions of the next seven browsers ranked by popularity. Click one or more of the buttons marked “Install” and you will have participatedinanexercise indemocratic accountability as potentially transformative to the web economyas any general-election ballot. That’s because the “browser ballot”, as it’s being called, could determine not only who controls our access to the world widewebin the future – but also the shape of the web itself. As Danny Sullivan, editor-in-chief of Search Engine Land and a long-time observer of the web, sees it, “We’re coming to a fork in the road where we’re being asked to choose between a web that is largely open and standards-based and one that is essentially run by companies.”

For years browsers have been the Cinderellas of the computing world, largely unnoticed conduits to the web. Most users stick with the one that comes with their computer (Explorer with Windows; Safari on the Mac); plenty are unaware there are even alternatives.

But since 2003, one browser has emerged from nowhere to challenge the dominance of the corporate giants. Built and
updated not by a multinational company but by an alliance of 250 staff and about 10,000 volunteers, and backed by a charitable foundation, the browser is free to download and its source code is open for anyone to inspect and modify –
all of which has made it the world’s second most popular browser, used by some 330 million people. And it has achieved that almost entirely through word of mouth.

The Mozilla Foundation’s Firefox, an elegant, feature-laden, customisable and, crucially, non-corporate browser that runs onWindows, OS X and Linux, has a global market share of 24 per cent, according to web analytics company NetApplications. That puts it behind Explorer at 62 per cent, but ahead of both Safari and Chrome, each of which hovers around five per cent. Across Europe, Firefox’s penetration is even higher, at 32 per cent, and in Slovenia, Macedonia, Slovakia, Poland, Hungary, Latvia, Bosnia Herzegovina, Ghana, Indonesia and the Philippines it is the number-one choice, with more than 50 per cent market penetration.

In the past year, Firefox’s popularity has risen even further. In July 2008, Mozilla earned a place in the Guinness World Records for the most downloads in 24 hours (8,002,530 of Firefox 3.0); in the two weeks following the launch of Firefox 3.6 in January this year, the upgrade was downloaded more than 40 million times. Andeven though its entire approach is the antithesis to that of the VC-backedWest Coast corporates, Firefox earns Mozilla real money. In 2008, according to its most recent audited accounts, Mozilla – which, remember, gives away its main product –announced a record income of $78.6 million. This comes mostly from fees paid by Google,Yahoo,Amazon and eBay to feature in the search box on Firefox’s toolbar, and a share of revenue generated by users clicking Google ads via Firefox-initiated searching.

All this would have been almost unimaginable by the small team of developers who began the Firefox project nearly 12 years ago as an attempt to rescue something from the ashes of Netscape Navigator, a browser that went from web domination to near death in just a few years. Navigator was developed by a 22-year-old software developer called Marc Andreesen in 1994.With it, Andreesen’s company, Netscape, had stumbled across a product perfectly designed to ride the world wide web’snewmass popularity, givingmany users their first taste of hyperlinks, web pages and the almost unimaginable scale of the information starting to be available online.

Navigator was distributed free for personal use, but sold to businesses via download and retail outlets. In addition Netscape got healthy revenues from its web-server software NetSite. By 1995, its income was doubling every quarter. On August 9 1995, the day the company was floated on the stockmarket – to many, the official start of the first dotcom boom– its share price rose from $28 to $75, valuing the company at about $2 billion. By December 1995, shares had reached $174.
Yet as fast as it had risen, Netscape fell.Within six years its market share had dropped from more than 85 per cent to
less than ten – and that residue was only due to users not bothering to upgrade. The reason? A simple change of business strategy taken by one Bill Gates, 1,300km north of Netscape’s SiliconValley campus, at Microsoft HQ in Seattle.

At the start of 1995, Microsoft appeared to have little interest in the internet with, reportedly, only four people working fulltime on developing a browser. Its ambitionswere focused squarelyonconquering the desktop throughWindows and associated programs such asWord. But by May, Gates was telling executives that the web
was where the company’s future lay. That December, four months after the Netscape flotation, the company released version 1.0 of Internet Explorer, a browser that, crucially, came free withWindows 95.

Explorer was a disaster for Netscape. Microsoft put huge resources behind its development, launching four fullnewversions in asmanyyears, bundling Explorer with every new copy of Windows and investing $150 million in Apple (effectively saving the company) in return for its making Explorer the default browser on the Mac operating system.

By January 1998, Netscape was finding it increasingly hard to compete and in a last-ditch attempted fight-back it
published theNavigator source code online in the hope that the emerging open-sourcecommunity would take the program – along with some associated products for handling email and IRC chat – and build something new. The company retained the rights to make commercial use of any code developed by outsiders.
The project was managed by a loose group of mostly former Netscape employees, brought together as the Mozilla organisation, named after Netscape’s dinosaur mascot. It initially had some breakthroughs in developingwhatwastobecometheMozilla Application Suite, but in 2003 the group decided to start again and build a new browser from scratch. It would take another three years to see a public release, but Firefox had been born.

It’s a Friday night in one of the tiny mediaeval alleys off Brussels’ Grand Place, and the three floors of the Deleriumbar are packed with revellers knocking back beers and shooting the breeze. The music is loud and the atmosphere somewhere between a festival and an indie music club. Yet the topics of conversation are more about GNU and bug-fixing than The White Stripes. The T-shirts feature obscure puns from the world of programming and many of the
friends catching up tonight have only ever met before online.

This is Fosdem (Free and Open Source Sofware Developer’s European Meeting), Europe’s biggest and grungiest opensource software conference. Anyone can come and there’s no registration, no name badges and no branded merchandise for the 5,000 delegates – and no one is really in charge. Instead, if you have something to contribute in the fight to preserve what the open-source community sees as the web’s essential freedom, you’re welcome.

There’s a sense of celebrationamongthe crowd– and not just overMozilla’s recordbreaking year. The increased popularity of web applications means that smaller, non-corporate players now have a real chance of taking on the big software companies at their own game. Predominantly young, male, articulate and impassioned, the Fosdem delegates are talking excitedly about “changing the world”, “making connections” and “keeping the mission moving on”. It could be an evangelical convention – although no one is wearing a tie.

The browser ballot is causing considerable excitement, with Mozilla seeing it as a long-awaited opportunity to introduce ordinary computer users to the idea that they have a choice about the sort of internet they interact with.Yettworecent developments are casting an uneasy shadow: Apple’s success with its closed approach to the iPhone and iPad – the latter announced a week earlier – and Google’s launch of Chrome, seen as a real competitor to Firefox that, some here are muttering, could kill theMozilla dream.

Apple tends to get short shrift at events like these. “You know why I am here?” says one delegate,waving an iPhone. “This! This is a machine to deliver money to the iTunes Store. The fact that I can buy andownsomething but not alter it or write software for it is just beyond the pale.”

Google tends to draw more nuanced responses. “Google is tricky,” says Matjaž Horvat, a developer based in Ljubljana, Slovenia, who helped translate Firefox into Slovenian in his spare time. “Sure, Chrome is opensource, which is good PR for the company, though I don’t personally think it is a very good browser. But then it takes you through to products such as Google Docs that are not open-source. So you have to ask, with Chrome, who really controls the web?”

This anxiety about Chrome pervades discussions at Fosdem. Google is reported to be spending $100 million advertising its browser, its first significant consumer ad campaign (Google would not comment on the budget). It has nearly 20,000 staff rather than 10,000 volunteers and its skilful aggregation of online users’ data makes it a formidable competitor.

“Google has a huge advantage over everyone else,” says Mark Surman, the Mozilla Foundation’s executive director, “because it is carrying out a real-time census of humanity. And there is a risk of it gaining a monopoly of insight that raises the lowbarriers to entry that the internet has created.”

Until mid-2008, Google was Mozilla’s mentor and champion, funding it through its support of Firefox. The two companies even had neighbouring offices in Mountain View, California, and Mozilla staff were able to use the
Googleplex canteen. Google’s funding of the foundation is guaranteed at least to the end of August 2011, and Mozilla has almost $100 million in the bank and plenty of search engines interested in that spot on the Firefox toolbar. But with its aggressive promotion of Chrome,Google has positioned itself right in the middle ofMozilla’s territory.

“I expect Chrome to gain market share of course,” says Mitchell Baker, chair of the Mozilla Foundation and a former lawyer who has been part of the Mozilla project fromthe start after joining fromNetscape’s legal team. “[Google has] lots ofmoney, lots of smart people, some very popular web applications, loads of determination and loads of data.With all of that behind them they damn right ought to put something useful out there. And it’s going to make us up our game, too.”

Baker stands out at events like Fosdem. Bubbly, engaging, hugely intelligent and incisive, and sporting what at best could be called an idiosyncratic hairstyle, she is also, at 57, decades older than most of the delegates. Having grown up in Oakland in the 70s, she read Asian Studies and then law at Berkeley, including spending a year in Beijing, where she developed conversational Mandarin, which she still keeps up. She was one of the first people to be recruited to Netscape’s legal team in 1994, and helped design the licence under which Netscape released theNavigator code. In 2003, when AOL, which had bought Netscape, closed down the latter’s browser division, she became president and later chairman of the Mozilla Foundation. Two years later she was made CEO of the Mozilla Corporation, a wholly owned subsidiary of the foundation, which co-ordinates the development of Mozilla’s internet products. She stood down from that role in 2008, to concentrate on running theMozillaFoundation itself, which is now primarily concerned with Mozilla’s policies and advocacy work. In her spare time, she trains as a trapeze artist.

Baker is a long-time advocate of open-source principles and is evangelical about her beliefs. At an early Fosdem session, she echoed open-source activist Richard Stallman and urged a packed seminar room to beware of a future for the internet that is “free as in beer but not free as in speech”.

“Even if everyone has free and open-source software, our project hasn’t finished,” she said, striding up and down the stage and clicking through OpenOffice presentation slides. “We need to concern ourselves withwho is collecting information about us and what can we do about that. Can I access it? Can I control it? If not, we still won’t be truly free.”

If this sounds demagogic, it is because Baker has understood that Mozilla’s strength lies in the number of people who go
along with its “project”. If you add to the 10,000 or so volunteers who actively write code for Firefox the people who test early versions before they are given a public release, you end up with a group of perhaps more than a million.These are impassioned evangelists who believe that the best future for the internet does not involve proprietary software, but instead uses programs and tools that can be pulled apart and reassembled by anyonewhounderstands coding. They believe this enough to give their time and energy for free in order to advance the cause. Baker would like more of them. “If I am going to make a choice about changing my online life,” she tells the Fosdemcrowd, “20, 30,40million people are going to have to make the same decision. This year we have to spread
our values to consumers.”

Baker has acknowledged that the launch of Chrome was “uncomfortable” for Mozilla. She is quick to point out that Mozilla and Google share a common goal: to unseat the closed, proprietary Internet Explorer from its dominant position. But Mozilla has sometimes been very public in its attacks on Google. In December, after the latter’s Eric Schmidt claimed: “If you have something that you don’twantanyonetoknow,maybe youshouldn’tbedoingitinthefirst
place,” Asa Dotzler, the Mozilla Corporation’scommunityco-ordinator for Firefox marketing projects, posted his response on his official blog. Dotzler quoted Schmidt with a link to the video where he had made his comments
and showed his readers “how you can easily switch Firefox’s search from Google to Bing. (Yes, Bing does have a better privacy policy than Google.)” The result was a lively discussion about both Google and Bing’s privacy policies – with neither search engine coming out particularly well. (Google points out that Schmidt was very specifically referring to the requirements of theUS Patriot Act.)

Privacy is a hot issue for Mozilla. It has announced plans to produce a series of icons that could be used on the web to alert users how any data they give up will be used. And grassroots open-sourcers such as Horvat are also unsure about Google’s deep-down commitment to open-source: “When you have someone like Google controlling access to thewebvia itsownbrowser so it can protect and promote something like Google Docs, you are in danger of creating a lot of monopoliesontheweb. That will crush innovation. The world is a better place when people can connect with and modify what they use.”

For Google, this misrepresents Chrome. “It’s very strange to suggest that Chromeis controlling people’s browsing or promoting Google Docs,” says Peter Barron, the company’s director of communications for northern and central Europe. “The briefest look at Chrome would show it’s utterly untrue. A major aim of Chrome is to make browsers better at running all kinds ofweb apps, not just Google products.”

At the Googleplex itself, though, there’s a certain empathy for the open-source activists. “There’s a problem, of course, as wegetsomuchbigger,” says ChrisDiBona, Google’s open-source-programs manager. “People don’t necessarily trust us so much straight out of the gate, or even like us. The fact that Chrome is open-source can challenge that point of view, but in the end some people want to see everything online open-source. That’s just a bit disingenuous.With Google Docs, for example, so much of that code is based on Google-specific architecture that to release it as open-source would just take too much engineering time. And anyway, we have released a lot of it, especially the UI [user interface] libraries and elements like that.”

Nor, the company insists, is itnowout to take on its old friend Mozilla. “We are not in competition,” insists Brian Rakowski, product development manager and to many the brains behind Chrome. “We are playing in the same space: we’re really excited about what Firefox has achieved in the past ten years. It has singlehandedly changed the market. But there came a point when we had to take on the browser project ourselves.”

Why this happened is up for up for debate, but both DiBona and Rakowski stress difficulties the Firefox team had implementing certain changes to the browser’s JavaScript engine, which, DeBona says, was running too slowly: “We had to make the decision to stop building more and more on top of Firefox and start again with a new core architecture.”

In fact , Chrome’s launch may have started a new symbiosis between Moz i l l a and Google. Building on the work of
Chrome’s developers, Mozilla has already reincorporated Chrome’s better handling of JavaScript back into Firefox.

“The added competition caused by Chrome means that everyone rises,” says Aza Raskin, head of user experience at Mozilla Labs. “Our job is to ensure that people have a choice, which iswhythe ballot is so important.” And, he adds,
rumours that Google and Mozillahavesomehowfallen out are untrue. “I have lunch with people from Google regularly and there’s a lot of friendliness.”

In fact, Mozilla may not need to be as worried about Chrome as, say, Microsoft. Later this year Google will launch Chrome OS, a pareddown, Linux-based operating system that will run on low-power netbook computers. Under Chrome OS the only application that runs on the desktop is a browser (Chrome, naturally) – all other computing
is done in the cloud. The result is cheaper and simpler hardware, very fast boot-up times (possibly as little as four seconds from switchon to surfing the web), a big jump in battery life and, Google hopes, more people using Gmail and
Google Docs. And whereas Chrome OS is not (yet) an alternative to Windows or Apple’s OS X – it will run only on specially designed hardware, for example – by giving near instant internet access, it is only really limited by what web
applications are available.
“In effect, you will only have one program running,” says Rakowski, who expects Chrome OS to launch in the second half of this year. “You will get a fast boot-up. Security is better as you won’t be able to install malware. And if there is a system problem, you can just reinstall the whole thing over the web.”

If that sounds a little familiar, it’s because Google will offer a trade-off similar to the one that has made the iPhone such a success: comfort over hackability. It’s a trade-off that worries the likes of Horvat and Baker. And whereas Baker is happy to acknowledge Apple’s achievements, Mozilla, she says, stands for something very different.

“People who follow Apple have avery strong connection with it,anaffection ifyoulike, just as people have a connection withMozilla. But its focus is on a product that is integrated, predetermined and highly controlled and we have different values. Real innovation comes fromopenness.We need to think about what it means to live online and who controls that experience. It’s a choice and we need to get people to understand that it’s a choice they can make.”

One field where this choice is being hotly debatedisvideo-compressiontechnology.Currently, rawvideo files are too large to distribute usefully across the internet, so a whole industry of video codecs has emerged to squeeze them as much as possible without a perceptible drop in quality. Many of these are used widely on the internet, but the only time ordinary users become aware of their existence is when their browser is unable toshowa particular video.

Now video-compression codecs have found themselves a hot topic in discussions about the next revision of HTML, the web’s mark-up language. The latest version, HTML5, due to be completed in 2012, will reduce web browsers’ dependence in showing video on third-party applications such as Adobe’s Flash.

Flash is currently the de facto video standard on the web – if you have watched a video online, you have almost ertainly used it – and some web developers are uncomfortable that a single company should have so much control over one of the internet’s key media. It’s unlikely that Adobe will pull the plug on Flash and stop us watchingYouTube, but among open-source activists there is a sense that Flash’s dominance is bad for the “free” internet, especially if you are a video maker as well as a video viewer.

The HTML5 developers are seeking to address those concerns by including in the code a new language for video that doesn’t require the use of Flash or any other third-party add-on. Instead, an HTML5-compatible browser will be able to decode video directly from the web page’s source code. (YouTube is currently trialling an HTML5 feed at youtube.com/html5.) Yet, perhaps rather inevitably, talks have stalled over which video-compression codec HTML5 should champion.
In opposite corners are two technologies: H.264 and Ogg Theora. H.264 is already widely used both on the web and elsewhere. It is stable and effective and, though commercially patented, will be royalty-free to internet users at least until 2015. (Most of the H.264 paten tholders’ income comes from licensing the codec to technologies such as Blu-rayand the cable-television industry.) Ogg Theora – named after the Max Headroom character Theora Jones – is open-source, slightly less efficient but effectively patent free.

Apple, among others, is arguing for H.264 on the grounds of stability. Mozilla is supporting Theora because of its openness and the foundation’s Chris Blizzard is warning of “GIF-like surprises”, referring to the moment in 1999 when
Unisys decided to start charging for the use of GIF imaging technology, for which it owned the patent. GIFs were by then used widely across the net and Unisys was proposing to charge site owners up to $5,000 for the use of its technology. The result was the demise of GIF and a lot of reformatting of existing images.

“It’s scary to think of a world where you would have to fork up $5,000 just to be able to use images on a website,”Blizzard wrote on his blog in January. “Think about all of the opportunity, the weblogs, the search engines (even Google!) and all the other simple ideas that became major services that would never have been started because of ahuge tax being put on [the ability] to use a fundamental web technology. It makes the web as a democratic technology distinctly undemocratic.”

Codecs and GIF patents may seem of little interest to the ordinary internet user, but Mozilla is hoping to persuade the rest of us otherwise.

“Software has a very large influence over what you do and how you think,” says Tristan Nitot, president ofMozilla Europe.“We needtomake sure that the software we use is serving us and not serving someone else’s interest. This
is the year that we are going to have to persuade consumers to think about the sort of the web they want. Otherwise
they may end up with one that is a lot less free and,whoknows, by then it may be too late.”
