The latest Firefox beta integrates much more fully into Windows 7, adding support for Aero Peek-enabled tabs, an enhanced Ctrl+Tab, and more. We’ll show you how they work, and how to enable or disable them.

The Aero Peek Tabs

If you simply hover your mouse over the Firefox button in the Windows 7 taskbar, you’ll see a list of all the open tabs. This works best if you only have a few tabs open—too many, and it’ll just stop showing them.

Enhanced Ctrl+Tab (optional)

The really awesome new feature is an enhanced Ctrl+Tab, but you’ll have to turn it on with a simple tweak if you want to use it. Once you’ve done that (detailed below), you can simply hit the shortcut key combination to flip between the tabs. Note that it only activates if you have 3 or more tabs open.

Ever wanted to be able to just start typing in the name of a tab in order to switch to it? Once you’ve enabled the Ctrl+Tab setting, you can use Ctrl+Shift+Tab to pull up this alternate tab switching interface, and then start typing in the name of a tab to filter it down.

Just like above, double-click to change between true and false.
