firefox will not open

I say crashing - it will not open. The closest I get is that it will say 'running troubleshooter mode', and then immediately close again before I can even see the actual browser. This issue does not occur with Chrome or DuckDuckGo, so it is not an issue with a Microsoft Family account. This issue is not related to missing or corrupted redist files, as I have installed all of the latest files there. I would like to switch to Firefox, as I use it on my phone.

Does it still happen if you rename firefox.exe to something else?

Have you tried creating a new local Windows user account?

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

  1. On the keyboard, press [Windows] Windows Key + [R]. This should bring up a Run window that contains a text field.
  2. In that text field, type %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

I am very sorry. I do not have a submitted folder. This is what I see instead.
