I've used this to help me less painfully debug browser issues for a year or two now, and now it's going on my parents' computer. Thanks, Erik!

By the way, some of the previous reviewers owe this addon more stars, as it now has the option to disable the hotkey (just blank the relevant fields in Options, in the Add-ons Manager).
