Rated 5 out of 5 stars

I was starting to think really hard about just using Chrome--well, probably Vivaldi--instead of Firefox. Mozilla are INSANE for not allowing users to customize keys. Agree with dotstar that Firefox is driving away much of its core audience.

I can't believe you got this working on Firefox for Android, too.

Thank you!

dotstar's link has some really useful stuff. I'd love to see a JS recipe for freeing memory (about:memory) via keyconfig...
