I'm on 59.0.2 now -- same problem :(.

Your observation appears to be correct: Firefox intercepts the keys and directs them toward a Quick Find bar instead of the document. The document never sees those key events, except perhaps the keydown for the first key pressed by the user.

I was re-using this fiddle for testing: https://jsfiddle.net/e4berr36/20/

Yeah, I hope the Mozilla team is listening because it's a serious problem -- basically any webapp, website, or extension that relies on keyboard events for hotkeys will not work as expected when this feature is enabled.

I guess it depends on what hotkeys sites use. The "Find as You Type" feature should not do anything if the user presses a key combination using Ctrl or Alt.

Also, does anyone use this setting on a regular basis? It's so annoying!

Nothing was picked up at all from my tests, which means combos using Ctrl/Alt won't work either.

Ah, never mind -- most combos work. The one I tried (Alt+X) didn't work because it's used by something else.

Still, IMHO this feature should not block normal JavaScript functionality. The least they can do is put a big notice on MDN or the Quantum page marketing this feature.
