I actually noticed some weird and potentially concerning behavior with Firefox Quantum this morning. I had a fair number of tabs open (~28 or so), and I restarted the browser so a change I made would take effect. I have FF set to show my windows and tabs from my previous session on start up, but it instead launched with a single tab showing my home page. Okay, no big deal, I'll just restore my previous session from the History menu. When I clicked on the history menu, though, I didn't see my most recent history, but instead a list of URLs from my bank. I assume this is due to a syncing issue with my Firefox account (I changed my banking password just to be safe), but it's still concerning.

That really does sound like a sync/profile issue, especially as it coincided with a failure to restore your previous session. I suspect you encountered some sort of corruption in your profile, and Firefox automatically restored one of the multiple backup copies it keeps to attempt to mitigate data loss. Still, always good to take precautions. What Firefox release channel(s) are you using? Are you running the same version across all of your sync'd devices? And can you share what change you made before restarting the browser?
