Mozilla Firefox 4 Beta 2 Released, Adds New “App Tabs” Feature
Mozilla has released the second beta version of its improved and redesigned Firefox 4 web browser. The new version can be downloaded from the release notes or official beta download page. It available for all supported operating systems (Linux, Mac, Windows) and now available in 24 languages. This second beta release also gives Apple Mac’s the same tabs-on-top look as in Windows. The one orange main button is still isn’t there in the Mac version, but the new toolbar formations are available now.
The most “talked about” new feature in Firefox 4 Beta 2 is “App Tabs”, which looks like Google Chrome’s “Pin Tab” feature. This “App Tabs” mode lets you keep an eye on sites you want to. Now, every tab in Firefox 4 has this new option “Make into App Tab,” on right-click to convert it into an “App Tab”.
Just like “Pin Tab” in Google Chrome, “App Tabs” reduces the normal tabs into the site’s favicon and places it to the leftmost side of the tabbar. Even though I couldn’t get App Tabs to re-appear when I relaunched Firefox, but Mozilla says they’ll stick, and show up in their own space.
Mozilla developers have also created a short video to show the new App Tab feature:
