Over the past 48 hours there have been at least ten breaches of my account. At first I assumed it was a breach of PayPal when someone used it to purchase a $3000 laptop on Newegg. I figured it couldn't be Firefox because Mozilla is pretty good with that sorta thing and because the only fraud was via my PayPal account. Well ... just over an hour ago someone attempted to purchase a $2200 laptop with my Amazon account using a completely different payment method, and I received several emails in both my Gmail and Protonmail regarding several accounts which I did not create. Firefox is the only browser I use, and I have passwords stored in it; I'll have to change all of them and remove them to a thumb drive. But Firefox appears to have a data breach ongoing right now. I can share screenshots if necessary but I will have to redact personal information and that will of course take time.

I suggest you contact the credit report people and report this.
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.
Also, contact all your credit card support and have your cards replaced.
I'm usually logged into Linux/Ubuntu so that's not likely but I have Malwarebytes on my Windows OS (dual-boot) and it's clean. While I will take all precautions including 2FA, removing my passwords from Firefox to a thumb drive, canceling the cards that were used, and notifying the state AG and possibly the US Attorney, that doesn't resolve how someone/s acquired passwords for several of my accounts, which until a few hours ago Firefox was the only place they were all stored.
Thanks for the tips though.
