Hello,

Here is how to restore all the info : Restore bookmarks : Click the Menu button -> Bookmarks -> Manage bookmarks (or press Ctrl+Shift+O). Click Import and Backup and select Restore. Choose a date from the automatic backups. (try to find a date before it all got lost)

Alternative bookmark backup : (more difficult) go to %APPDATA%\Mozilla\Firefox\Profiles\ (type win + r then paste this) find the bookmarkbackups folder, then find .jsonlz4 files and replace accordingly.

Restore passwords : (windows) go to %APPDATA%\Mozilla\Firefox\Profiles\ (type win + r then paste this) find logins.json and key4.db and copy and paste it into your current profile (save a copy of the broken ones somewhere else and replace it with the backup)

No, I actually tried that earlier. It does not work. But reference a bookmark folder. Not sure where to find. I really need to find a way to accomplish this. Thanks for any further info

ok, found the bookmark back ups folder. In in separate search found recovery,jsonlz4 files. But a bunch files showing up all dated 4-11 when upgrade installed including upgrade jsonlz4 file. I don't know how to proceed now & worry if I close windows won't find this stuff again.
