I'm not sure if this is the cause but a few days after windows update my firefox crashes. I restart it and only screen opens and doesn't respond. Deleted Firefox, did fresh install. Firefox starts again but as soon as I log in my account, crashes again. Delete firefox and again fresh install. I don't login, I save 3 bookmarks and it crashes again. Delete firefox again and fresh install. But now firefox starts in the background (seen in task manager) but does not open a window. Download latest installer and try to install but now install says, "something went wrong" during the download. (could be the enterprise network here) this I tried a few times but no success.

So I download Firefox 101.0.1 ISO and install. But again running in background and no window.

No I didn't get crash reports. But I put the same question at the microsoft forum. Apparently there is a bug in the last windows update that was causing this. I deleted the last update and everything is working like before.

Thank you everybody for your help.

OK so apparently my mobile hotspot is preventing firefox or any webbrowser to enter the internet of even start.

What security software? Reboot and try a different user account to see if you have the same issue.
