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.
