Firefox 4 Beta 2 with App Tabs and tabs on top for Mac
Firefox 4 Beta 2 was just released, and you can grab it from the Beta page.
Every tab now has a “Make into App Tab” command in the context menu, which shrinks the tab down to just the favicon and puts it on the leftmost position (similar to Chrome’s pin tab feature). Also, tabs on top have arrived in the Mac version. I couldn’t test it myself – share your thoughts in the comments, Mac users!
