I have recently downloaded Firefox on Windows 11. When I first installed it, it worked fine, but it crashed and I couldn't open it again. When I try to open Firefox, a "Troubleshoot Mode" window flashes for less than a second and closes. About 8 months ago, on a different computer with Windows 10, had the exact same problem. I thought it was just because it's ancient, but it does the same thing on my well-functioning computer. I have tried the Microsoft Store Firefox and downloading from the website. I have reinstalled and restarted several times, and my computer is up to date. I do not use any 3rd-party security software. I still cannot launch a Firefox window at all. I love Firefox on mobile and I really want to use it on PC. Thanks for your help!!

Try to start Firefox in Troubleshoot Mode to see if that works.

  • Windows: hold down the Shift key while starting Firefox
  • Mac: hold down the Options key while starting Firefox

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.

Your Microsoft account may have parental controls enabled which limits what browsers you can use, you could try to get this limitation removed or create a new account. Renaming firefox.exe to something else can get it working but this will break DRM protected videos.
