How come my registry cleaner caused FireFox to stop working?

by on June 6, 2012

Q: I used the 1-click option of Registry Mechanic registry cleaner, and now Firefox is almost totally disfunctional. I get no headers or advertisements–just a list of options on the left side of the screen for most web pages. A few seem to be OK.

I uninstalled and reinstalled Firefox and get the same thing. Internet Explorer was not affected as far as I can tell. I emailed PC Tools, but have gotten no response. Any ideas?

    Try using Firefox safe mode to see if that helps isolate the problem:
