Jennifer Boriss writes, “Dão Gottwald has been working for a while on his Ctrl-Tab Firefox add-on. Ctrl-Tab has two parts: a filmstrip that allows the user to quickly jump to recently used tabs, and a tab preview mode. These features have been widely used, and lately we at Mozilla have been working to give them a home as a Firefox feature. We’re happy to announce the filmstrip of recently-viewed tabs landed today and will show up in tomorrow’s nightlies as a new Firefox feature.” It is currently expected that this feature will first appear in Firefox 3.1, and there’s lots more information about this new feature and how it will affect Firefox users’ workflow at Jennifer’s weblog.
