No problems so far...although the metro version development is being dropped, it was a bit quirky to get used to. So I went back to version 27. I just re-downloaded it and ran it with out uninstalling FF. This is where all the issues started. At first my got this error..... So I went through my PC with every scan I have....then went through the registry and completely uninstalled anything related to Mozillia. I then ran Ccleaner registry cleaning tool. So far so good, then rebooted, re-installed FF and now I get this error.... The only way I can use FF is right clicking the icon on the desktop and select run as administrator.....What the H$#% can I do to resolve this issue.
