The app is very helpful but has stopped working in the new version (FF 67.0b3 64-bit). Hope you revive the app :)

It does not work on many sites (mostly not on mozilla sites). Can't remap original hotkeys, like you can't remap CTRL+T and CTRL+N.

Works out of the box with quantum. Seems to be well maintained. Nice UI.
