Firefox crashing immediately after install, won't open
I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).
I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

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.
- On the keyboard, press [Windows]
+ [R]. This should bring up a Run box that contains a text field.
- In that text field, type %APPDATA% and press Enter. An explorer window should open.
- From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
- 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.
- Open the most recent 5 files with a text editor and copy the IDs.
- Paste each ID with bp- into the reply window on the forums.
Thanks in advance!
You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.
There isn't a folder called submitted in crash reports (even though I have submitted them). There are folders called events, glean, and pending, a file I can't determine the type of named InstallTime20250529122813, and a .log document named submit.
InstallTime20250529122813 contains the following text only:
1749212441
The .log document only has the following:
[WARN crashreporter::net::ping] not sending legacy crash ping because no ping directory configured [WARN crashreporter::logic] not updating the events file; no events directory configured
Nothing I can find has an ID, unfortunately.
