Well two updates ago I had the problem of firefox not being able to connect to anything on the net. Next update fixed everything. Now with this latest update (v74.0.0.7373) it will not launch at all. Event viewer is telling me this: Faulting application name: firefox.exe, version: 74.0.0.7373, time stamp: 0x5e662a88 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x00007ff9ce90012a Faulting process id: 0x11b4 Faulting application start time: 0x01d5f90498961d60 Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: unknown Report Id: d6797f56-64f7-11ea-8381-00241d8dcb2d Faulting package full name: Faulting package-relative application ID: This is on Windows 8.1 64bit version. What to do what to do...
