Tabhunter - Find and Switch between Firefox Tabs Easily

Tabhunter is like Quicksilver for tabs.

The current version of Tabhunter uses the same keyboard shortcut as OS X's "Special Characters" character palette. An easy workaround is to create a dummy entry in the Keyboard & Mouse preferences (in the "Keyboard Shortcuts" section) that doesn't do anything but uses the same Command-Option-T keyboard shortcut.
