I just noticed this as of a few minutes ago, & I'm not sure why it's there. I saw it as I was doing some research, & I didn't get kicked off line, or anything like that. I saved my links, & shut down Firefox, & then restarted it, with no problem. And I had no problem getting to this forum. Over the several years of using Firefox, I've never seen this before. When I clicked on the warning icon, it took me to Mozilla Accounts, & then wanted me to download a recovery key??? The page disappeared, & then wanted me to sign back in, & then it refused my password three times! It reappeared, & then wanted me to "Synch", my phone, & PC, which I'm not going to do. So,... What was/is this latest issue with Firefox about?
