I am unable to use my keyboard for typing characters on any firefox page including the google search bar. I am able to type without problems on IE, notepad, word etc etc.

I have windows 10 installed on my PC and also Win XP on a dual boot - the keyboard functions fine on Firefox with XP. 

I have tried resetting and installing from scratch with no effect and have latest Firefox version. I use Kasperski IS latest version. Any help gratefully received as it’s a pain having to type everything into notepad and the copying & pasting!

The only keys that respond are the backslash and the period on the numeric pad..

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?


Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?

Some have reported that pressing F9 and the Windows key simultaneously one or more times has worked to fix issues with the keyboard not working. If this doesn't help then close and restart Firefox or reboot the computer (you may have to reboot more than once).
