Version: 0.1.1iswitchb-tabs brings Emacs' iswitchb-mode to Firefox. Lets you easily switch between tabs by just typing part of the tab title.
Operating System: Mac OS X
Great if you keep a lot of tabs open in many different windows, or if you just want to conveniently switch tabs using only a few keystrokes.
Just press F9, or find it in the Tools menu, and a window that lists all your tabs (in every browser window) appears. Start typing part of a tab name, and the list will narrow down.
You can use the up and down keys to find the tab you want. That tab will be selected, and the browser window the tab is in will be brought to the front.
