Fire fox keeps crashing on bootup
Firefox keeps crashing, when I boot it up a prompt appears for half a second asking if I'd like to go to safe mode, but the prompt window instantly closes after half a second. I have tried refreshing the app, uninstalling, and reinstalling, and nothing seems to work. The app was working a day before this. How can I get it to work properly again? It is worth noting that I had to ask my parents to allow my computer to use firefox the day before all this happened, but after that, it worked fine. Only now there are crashes every time.

What happens under a different user account on that pc? Have you tried Windows in Safe Mode?

Are you on Linux, Windows, or Mac? What version of the browser? Have you tried safe mode? Firefox safe mode: Click the menu button, click Help and select Restart with Add-ons Disabled…. Firefox will start up with the Firefox Safe Mode dialog.
I'm on windows, Firefox doesn't open at all, I can't click on any menu button because the app itself doesn't open at all.
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.
In that case, I would install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads
I'm sorry but that didn't seem to work either. Those files are all installed, I tried to fix the old files but reinstalling them but that didn't work either.
Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
Configure firewalls so that Firefox can access the Internet. {web link}
this doesn't seem to be the problem, the app still crashes on startup
If you can't get Firefox to open, you will have to do this the hard way. https://support.mozilla.org/en-US/kb/mozillacrashreporter
Open the file browser / explorer on your computer. Note: You may have to enable Show Hidden Folders / Files. Enter this in the address bar;
Windows: %APPDATA%\Mozilla\Firefox\Crash Reports\submitted Win 7/Vista: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Crash Reports\submitted Win XP/2000: C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Crash Reports\submitted Win 10: Press <Windows> + R on the keyboard. A Run dialog will open. In the Run dialog, type %APPDATA%\Mozilla\Firefox\Crash Reports\submitted <Enter>
Mac OS: /Users/<username>/Library/Application Support/Firefox/Crash Reports/submitted

What happens under a different user account on that pc?
There doesn't seem to be any crash report on file, only installation reports
i have this exact same problem and none of these solutions have worked for me.
