This morning, addons.mozilla.org reached a huge milestone: we served our 1 billionth add-on download since we started keeping track of downloads in 2005.
This number only includes downloads from addons.mozilla.org, but as many add-ons are hosted elsewhere, we can be sure the actual number is even higher. This is a very exciting week for Firefox add-ons, with the launch of Fashion Your Firefox yesterday, offering a new way for first-time add-on users to customize their browser.
This amazing feat was made possible by the huge community of add-on users, developers, and enthusiasts, as well as non-Firefox applications that embrace Mozilla add-ons like Thunderbird, SeaMonkey, Sunbird, Komodo, Flock, and Songbird, to name a few.
At 1.5 million add-on downloads per day and increasing, I’m confident our next billion will arrive even more quickly than the 3.5 years it took for the first. If you’re not using an add-on yet, try one out. They’re pretty popular.

what extension had the billionth download?!!
What an awesome milestone – very cool indeed.
I think the awareness of addons is spreading down the foodchain, from geeks to more normal
people.
At work I was really surprised to see that my colleagues had gone and installed some addons that I’d never told them about, all on their own.
love it!
Download Helper is by far the best add on for anything..ever. You guys need to advertise that more, it’s flawless. Firefox ftw.
@dietrich – It’s not really possible to tell, but I like to believe that it was this one:

It’s a great achievement
Keep the add-ons coming!
Does that include every time I update an add-on?
Because every release of firefox inevitably breaks a bunch of plug-ins, meaning the authors have to make a trivial update to them just so they’ll keep working, meaning they get re-downloaded.
Congratulations on 1 Billion served! I guess I’m one of the billion, but will have to ask my son.
Cool, but what exactly is an add-on? only extensions? extension and themes? extension, themes, plugins and search plugins?
(It is confusing, for Fx pref window, add-ons=ext/themes only. for add-ons manager, add-ons=ext/themes and plugins. For AMO, add-ons=ext/themes/plugins/search)
