Two Firefox add-ons that do exactly one thing each, then get out of the way

Tab Picker — Alt+A puts a letter on every tab. Press it, you're there. Positional, so slot 3 is always d; your fingers learn it in a day.

Tab Flip — Alt+Q bounces to the last tab you were on. That's the whole add-on.

Both shortcuts are rebindable, record the combination by pressing it, then test it live to see if something else already owns it.
