I don't know what I would do without the awesome Web Developer extension for Firefox.
Suddenly my shortcut key for "Display Element Information" stopped working. This is pretty much the thing I use the most. Long story longer, the conflict is AdBlock Plus (another amazing extension).
In about:config I see an entry to alter the shortcut key for the function in Web Developer, but I do not see an entry to alter the shortcut key for AdBlock Plus. Boo!
Any solutions out there? I haven't found any. (My hopefully temporary solution is to remap Display Element Information to ctrl-shift-v which doesn't seem to be used elsewhere with my set of add-ons)
What I did find is a consolidated registry of keyboard shortcuts for extension authors. Bravo!
