Firefox Not Responding on Startup

💻 Help

Hello, I just started having a weird issue with Firefox today where when I start it up, it immediately stops responding. Other browsers work, but not Firefox for some reason.

I saw similar posts online that suggested accessing the about pages but I can't even get there, Firefox stops responding whether opened in troubleshooting mode or regularly. I tried to do a clean install and deleted all files from Program Files and Roaming AppData, and it still stops responding on startup.

I have a computer running Windows 11 with an AMD hard drive, I can update with system specs if necessary but I don't think it's a hardware issue. Help would be appreciated, thank you!
