Alt-KEY handled as KEY on Firefox

[kitaev]

Hello,

recently I've noticed that keypresses with Alt modifier are treated as those without by Vimium Firefox addon.

For instance, Alt-D is processed as 'D', Alt-F as 'F'. Adding "unmap d" helps, but obviously disables 'd' functionality.

I can reproduce this as well. But I first noticed that Alt-1, Alt-2..Alt-9 don't work for switching tabs any more. So I suppose these two are related and it makes sense to add the comment instead of a new issue.

I have the same specs as @kitaev.

Update: I can no longer reproduce the issue on Firefox 68.0.1.

I'm experiencing the same issue. Adding an exception rule with pattern "*" and keys "12..9" fixes the Alt-number problem.

Having the same problem, but with d for scrollPageDown. I commonly use ALT-D for accessing the address bar, but now it just scrolls down...

This happens on Chrome, too. It causes Chrome's main menu key binding Alt+F to not work. Pressing Alt+F brings up Vimium's "follow" command, as if just f were pressed.

f and Alt+F are distinct commands and should not interfere with each other.
