Thank you. I've been using Dorando KeyConfig for ages (even when it stopped being officially supported, and I had to sneak it in to Firefox) - I _hate_ backspace taking me back a page any time a text field isn't in focus, and the Alt-arrow back and forward drives me nuts (a two-handed shortcut? Really? I know, there's an Alt key on the right too - I never use it). I was afraid I'd lose my fixes - Alt-z for back and Alt-x for forward - with version 57. Thank you so much for making this!

It is a little bit complicated, because the text fields for creating a shortcut will happily take Alt or Backspace and then ignore it because it's not the key (which is alt or backspace - no caps). I had to go round a couple times to get that set up right (the instructions on the right are very helpful). But now it works, yay! Saved my sanity.

Acceptable alternative to Dorando Keyconfig in wake of FF v57.0

F1 for Go Back and F2 for Go Forward have always seemed like logical keyboard shortcuts to me, and for some reason Firefox has never exposed those actions for the OS to hook onto. This add-on is pure genius, not just for my reasons, but for so many more. Great job. Saved me the time of digging into WebExtensions myself tonight.

For some reason, this add-on is hardcoded to only work in Firefox versions 50 or earlier:

Update: The problem was fixed. Thanks!
