Three new features are now available to Windows 7 users of the new beta release of Firefox. Firefox 3.6 beta 1 introduces enhanced previews for both the new Windows 7 taskbar and the tabs.

The taskbar previews for tabs brings Firefox into parity with Internet Explorer 8, allowing users to see and select their open tabs via Aero Peek. The obvious limitation with this feature is how it impacts the display when you've got a high number of tabs open. As you open more tabs, their preview panes will shrink.

While the taskbar preview will work without manually changing settings in about:config, the others will require a bit of fiddling. As such, they're not recommended for new users, or for those who just aren't comfortable tweaking the about:config.

The enhanced Control + Tab will now show you a preview window of your tabs, as long as you have three or more tabs open. To activate it, go to about:config, search for browser.ctrlTab.previews, and double-click on it to change it from False to True. Then restart Firefox, and the CTRL+Tab hot key will give you Aero-style preview pane of your tabs.
