Can't open Firefox - error re "platform version '120.0.1'
Hello,
Clicking to open Firefox gives me the following error message:
Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0
Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631
Thanks! Julie

Hello. It seems that you have a mixture of old and new files. I suggest that you remove Firefox and reinstall it. You may want to consider a 'custom' installation.
