I'm trying to customize my keyboard layout on Windows. I have finally installed my new layout. However some of key combinations doesn't work on some applications. One of them is Firefox. It seems it doesn't handle chained deadkeys. And for some reason RightAlt + Q which sould produce "\" produces some wierd combination – this parcitual wierd issue is specific to Firefox. I can send an installer of the keyboard.

Thank you for help

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

It seems that this it not matter of configuartion. I have tried in safe mode with same result. Actually it seems that Firefox implement keyboard input itself on low level and that chained dead keys are not supported. See https://bugzilla.mozilla.org/show_bug.cgi?id=791300.

Sorry, this question is a duplicate of my another question https://support.mozilla.org/en-US/questions/975593?esab=a&s=&r=1&as=s. I thought that this question post wasn't created.
