Keyboard Shortcuts In New Firefox Not Working

laserbeak-10

Keyboard shortcuts like "E" & hotkeys in general don't work on Firefox Developer Edition v65b1. Also unrelated: My userChrome.css script to bring tab bar below, et. al. scripts aren't working anymore, though I can Fullscreen without the hover menu. Or is it just me ? P.S: Yep works in Edge, so it's a problem in Firefox, or _my_ Firefox config.

This seems to only affect the developer version, i can observe the same issue here. Regular Firefox works fine from what I can see.

Obviously the usual caveat: Developer Editions are not supported.

I have to press Shift + the hotkey (E for instance) for it to work ! In games like The Settlers Online, the hotkeys haven't changed, they work normally —which seems strange.
P.S: It's only the base-switcher hotkeys (arrow keys (left + right)) that's the issue —there's no workaround for this.
