Firefox taken over by a ransom scam
Firefox is completely broken for me now. I somehow clicked (I have MS, I click randomly sometimes) on a site that flashed red, showed a bunch of scary looking stuff, and demands an authentication to unlock my browser. I think it's trying to lock my computer, but I have to kill it with task manager as soon as it starts up again. Now I can't open Firefox to do any of the things the troubleshooting guide recommends.
What do I do? I saw a post that said reinstalling doesn't help because the bad thing is now in my profile.
I was just getting to use Firefox, thinking I would change from Edge and Chrome. I've just gotten all my passwords in, all my bookmarks set up (no, in 2020 they still can't pull in your favorites from another browser, but it says it did.)
I've had this kind of thing come up with other browsers, and forcing them closed worked. This one seems to let them in deep enough they have taken over. I have pay Avast and it scanned the browser and said it was fine.
Any ideas? If I'm going to remove the program, I'm not sure I need to put it back. It hasn't done anything really better than Chrome, and this episode is certainly an example of worse.

If it's like the fake FBI/Interpol browser lock page, A way out of a trap page is to (force it if needed) Close Firefox. Wait about 20 seconds for Firefox to finish closing. Right-click on the Firefox icon and select Open New Window. +++++++++++++++++++++++++++++++++++++++++ Sometimes this works. If it opens, close it by Menu > File > Exit. This will flush out that web page from the Session Store.
You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no
Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
