Everytime I try to open my firefox 3.6.3 it fails and instead an error message appears stating that "mozcrt19.dll" is not a valid image. I'm running windows XP. Firefox has been running fine for me for over an year now on the same machine and same OS. Uninstalling firefox and reinstalling firefox from mozilla site has not helped at all. == User Agent == Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; MS-RTC LM 8)
