Re: Updated Firefox but it disabled Microsoft net framework.. can't even access my Control Panel, now. What do I do?
I doubt that Microsoft .NET Framework Assistant has anything to do with your Control Panel issue. You can turn it back on; see the articles below. New versions of Firefox give you the opportunity at install to activate or not activate Add-ons, especially those added by third-party programs like .NET Framework. As for your other applications not working, that is something for which you will need to determine the causes.
