KeyConfig for Firefox lets you rebind your keys and shortcut keys.
If you’re wondering where keyconfig for Firefox went, you can stop looking. I searched for a while and then realized that, to the best of my knowledge, it’s not in the Mozilla Extensions directory / repo.
Here’s the keyconfig for Firefox that I’m used to:
I’m using Keyconfig on Firefox 3, Firefox 4, and Firefox 5 and it seems to be working fine.
You can Install Keyconfig for Firefox by clicking on the .xpi file.
About Keyconfig
keyconfig allows you to change keyboard shortcuts. Firefox, Thunderbird, SeaMonkey, and any other XULRunner Application keyconfig adds the ability to create new or modify existing shortcuts defined by aelement, but only changing those which itself call a function (those with a command or oncommand attribute) has an effect (all others fulfill only cosmetic purposes it seems and are grayed out). The configuration screen can be accessed via Tools > Keyconfig (in most Applications), the Add-ons Manager, or Ctrl+Shift+F12 (Command+Shift+F12 on MacOS) from the main window. Currently there is only one list of modified keys per application, so changing a shortcut in one window will also affect other windows if they use the same key name.
In the Mozilla Addons Search, you Martin Petricek, but that addon looks like it still needs some work as the comments say it’s buggy, and it apparently does not work for Fire Fox 5.
