Tab Kit is an add-on for Firefox designed for the sort of person who likes to keep a ridiculous number of tabs open. If you've ever tried open a few dozen tabs, you're probably well aware that Firefox tends to cram the tabs closer and closer together each time you open a new window until it's almost impossible to tell which tab is which. Tab Kit will keep each tab wide enough for you to view a preview of the page titles. It achieves this either by letting you roll your tabs over into a second row of tabs. Or a third or fourth row, if you don't mind losing some more screen real estate.

But that's just the tip of the iceberg. Tab Kit will also let you move all of your tabs over to the Windows sidebar, or to the bottom of your screen. You can also:

• Adjust the size of your tabs
• Switch tabs with your mouse scrollwheel
• Reorder your tabs by domain, last loaded, last viewed, order of creation, origin, or title
• Group tabs
• Decide whether to display a close button on all tabs, just the active tab, or no tabs
• Highlight unread tabs
