Hello there, I hope this problem to be solved soon. Check this article might help you: "Recover user data missing after Firefox update" https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update

Thanks for the reply, but there are no old profiles I see in about:profiles. I think it has something to do with the new release and changing up the system they had in place. My laptop still has most of my passwords so I can recover some of them from there.

@davidsopala Hello again, I don't want to lose hope to restore your data. And because we don't know the exact reason why this happened (see the paragraph between " "), I encourage you to see theses questions from people had the same problem. I believe you will find your solution in it.

(I know that the problem happened after the update, but what in the update that made the problem? and why it's not universal problem for all users like me for example?)
