opened firefox this morning on my pc to watch youtube while getting ready. It was 5:30 am so Iwasn't quite awake and I don't really remember what happened. I think I opened firefox and went to youtube, I was asked to sign in to see my subscriptions on youtube. I singed in. I keep my zoom at 160% big monitor, it was back at normal 100%. My bookmarks, cookies, addons and passwords are gone. I tried to restore to a previous version, but there isn't one. The newest save in my old firefox folder is from 2017. What happened?

Hi coramonster12, sorry to hear about this problem.

If you haven't already, could you close out of Firefox and do a normal Windows shutdown and restart to complete any pending updates and release any file locks.

If Firefox again starts up without your data, could you check whether your stuff is available in a different profile, as follows:

Profile Manager Page

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

This page should list at least one profile and could list many. Each will show links to a pair of folders; please ignore those for now.

The profile that Firefox is currently using will have this:

This is the profile in use and it cannot be deleted.

Actually, please do not delete anything here, don't use any Remove buttons.

Do you have another profile named default or default-longnumber listed on this page? If so, you can check whether it is the one you were using recently by clicking its Launch profile in new browser button.

If it isn't what you want, simply close that new window.

If it IS what you want, back on the about:profiles page, click the Set as default profile button for that profile so Firefox uses it automatically at the next startup.

Any progress so far, or do we need to keep looking for your data in some other places?
