Hello,

From what you have written in you question it would seem that you already did but did you follow the steps highlighted in these two articles?

Restore bookmarks from backup or move them to another computer and the Recover lost or missing Bookmarks article.

Sorry if you have already done it but sometimes it is worth asking the question.

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

• https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

• Do NOT click any Remove button on this page.
• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

Firefox 67 and later can use a dedicated profile for each of the Firefox update channels and will lock the profile, so it can only be used by Firefox in a specific installation folder. For Release versions this profile would be a xxxxxxxx.default-release profile, profiles used in older Firefox versions usually used a xxxxxxxx.default profile (a refresh adds a time stamp).

I tried the restore button but the only files was from yesterday, no earlier

There is only one profile!
