Firefox wouldn't start up after computer was shut down. It keeps coming up with Mozilla Crash Report. I have uninstalled Firefox, I have manually deleted all Firefox folders. Everything listed on this site I have tried. When I try to install Firefox again it comes up with the crash report again on install.

The crashing thread in all three reports have a call to WindowsDllBlocklist.cpp:712 at to bottom of the thread. So it is possible that you have files that are on the DLL block list and that aren't playing nicely when Firefox tries to (re)move them.

Boot the computer in Windows Safe mode with network support to see if that has effect in case other software is causing problems.


Do a malware check with several malware scanning programs on the Windows computer.

Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
