Mozilla has released yet another Beta for its firefox 4. This time it includes tab on top for Mac users.
Features to look for include
A new HTML5 parser and full support for web video, audio, drag & drop, and file handling means Firefox 4 is ready to run the best web apps of both today and tomorrow.

Add-Ons can be installed without restarting the browser, and can be developed more easily using the new JetPack SDK and js-ctypes.
Firefox provides uninterrupted browsing for Windows, Linux, and now Mac when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins. If one of these commonly-used plugins crashes or freezes, it won’t affect the rest of Firefox. Instead, you can simply reload the page to restart the plugin and try again.
You can simply update from firefox 4 Beta 1 to Beta 2 or can
