Where are my favorites and my extensions? How do I get them back?

ALL THE FAVORITES that i need for work, for research, for personal use, websites I saved...all gone. All gone. I do not even know what they were at this point, as it took months to find them and noone can remember every website. Government websites.

This is is literal disaster and sabatoge. You can't do this to users. This is sabatoge. It is just like walking into someone's house and stealing all of their paperwork and passwords. I have no way to fix this. I cannot find the extensions, favorites, ANYWHERE. I do not know passwords to accounts. I do not know pages I MUST use for personal and professional use. Everything is GONE.

You cannot expect or require everyone who uses your Firefox product to be a techy. I feel so betrayed at a visceral level. You have royally just screwed me over right now.

Anne, refreshing should have placed a folder named something like 'Old Firefox Data' on the desktop. Did you look for that name specifically? If you can find this folder then you can try the steps here to restore data from it. https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

If you cannot find that folder then alternatively you could try the steps in this article to see if your bookmarks etc. can be found in a different profile. https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update

(Sorry, but there are probably no simpler fixes.)
