I'm running Firefox on a Windows 7 machine. Firefox won't open following the latest update. I've read the help articles and it seems like I need to create a new profile because my settings have likely been corrupted. I'm unable to open Profile Mgr, even when using entire directory path in cmd line. I've tried the following commands in the command line:

firefox -p "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p

Nothing happens with either command.

I'm also running Norton Internet Security. I read a help article Re Virtual Browsing features possibly causing a problem. The article said to check the virtualization setting in the internet security software and to clear the virtual cache. I went thru all of the settings menus in Norton Internet Security version 21.6.0.32 and I didn't see anything that looked like 'virtualization" settings, so I assumed that this doesn't apply to me.

If you have any ideas, I'd sure appreaciate your expertise!!

hello arcandl, when firefox isn't launching after you double-click on the shortcut this is sometimes also a sign of malware being active on a system. you might want to try running a scan with some different other security tools like the free version of malwarebytes and adwcleaner which are specialised in removing adware and browser hijackers.
