I've had this problem for a while and it's kept me from actually using the program. At any given time when I try to run the application, it never lasts for more than a couple seconds before it suddenly stops with no warning. Whenever I get these crashes, the Crash Reporter never opens. Because of this issue I can't open it in troubleshooting mode. At this point I have tried fully resetting my PC twice, uninstalling McAfee, had multiple malware scans, and have uninstalled and reinstalled Firefox itself multiple times. I'm really not all that good at operating computers, I just kind of know how to navigate files. I don't know what else to do at this point.

Did you recently uninstall an application that was using Visual C+ runtime components?

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017, 2019, and 2022":

Download the latest vc_redist.x64 and vc_redist.x86 files.

You need to reboot the computer.

I just tried this and that worked, I renamed my exe file and the sig file to OpenBrowser.exe and OpenBrowser.exe.sig respectively and now it seems like Firefox is working. Thanks so much for your help!

That's funny.  ;-)) I blame McAfee.
