Firefox browser does not function when logged into AD domain. It works fine if using local account. This was not an issue until recently (perhaps a month). FW settings are open and websites are functional on other browsers, but after an Windows Security Update Firefox will not load any pages. It will not even open Settings tab. No bookmarks work.

I have uninstalled and tried to reinstall, and the windows update or the package install crash before install initiates. Logged into laptop local and was able to install, but when using domain account the problem reoccurs. Note, browser was functional until windows patch and indicators are of some .NET framework corruption.
