My firefox browser stopped working today. I've tried uninstalling and reinstalling twice. Firefox will open once after a reinstall, but opening web pages is intermittent. When I close firefox and restart, nothing happens. If I go to task manager I can find some firefox processes running, but nothing is happening on my screen. I don't get any type of error message, just nothing. I've been using firefox without issue until today. I have a dell XPS 13 with Windows 10 Home.

Yes I do use webroot and have been for years. Not sure why this is just now happening, but I will look into it. Thanks.
