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 free to use malware scanners. Each works differently. If one program misses something, another may pick it up.

There are system-level keyloggers, of course, that's the classic.

One way to log keystrokes in a browser specifically would be using an extension. Extensions do not have direct access to Saved Logins, but they can inject scripts into web pages. You might have one or more extensions installed that have the highest permission of "Access your data for all websites". While the vast majority of extensions respect you and your privacy, some malware extensions may watch your form entries and exfiltrate what you entered to remote servers. Keep a close eye on your extension collection and be cautious about adding new ones.

Have you tried the malware scanners I wrote about?

As to the stolen data, all we can recommend is you change ALL passwords immediately and verify your personal data on those websites.

Just download each scanner you want to use and run it. All are free to use. A subscription opens special features and options.
