Alright, so I've tried installing a previous version, deleting all files in Local, LocalLow, Roaming, and Users/Program Files related to firefox, even deleting registry keys, but every time I try to use firefox I just get a flickering loading circle on my mouse. I open task manager, and see that firefox is in there, and constantly opening and closing new processes on itself. I try to kill the process and cannot as whatever one I'm trying to close is already dead and a new one takes its place.

I have also done malware scan, virus scan, and a boot-time virus scan as stated.

Did this start with the current Firefox version? Firefox Release 74.0 March 10, 2020

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Booting Firefox in safe mode did nothing. Booting computer in safe mode with networking allowed me to open Firefox, but I could not visit any sites. And when I restarted afterwards, it tried to open itself resulting in the perpetual starting-stopping process deal I mentioned in my original post. And yes it started with this version, though now it seems even the version works does not work for me.

This could mean that one of the other programs on your system is causing the issue. As a test, disable your protection programs.
