Windows 7: I need help with firefox upgrade and a "XRE fuction" issue

I need help with firefox upgrade and a "XRE fuction" issue

Hello all. This morning my Firefox auto-upgraded to v20.0. When I tried to start Firefox up I got a error message: "Could'nt load XRE functions" See screenshot

I understand this to be similar to the XUL runner issue.

I uninstalled FF again and tried to use revo to completly uninstall FF, but it was not listed.

I use ZA Extreame security, and read that it may be the problem, but it never caused me problems before.

Any help to get FF working would be greatly appreciated!

PS- sorry for badf spelling, IE9 evidently has no built in spellcker!!

I tried the web solutions i read about turning of my ZA browser virtualization, which solved the XRE function issue, leaving a new issue of not finding my profile, but i solved that and BAM FF works now!!


I will report back shortly if the issue is solved!!
