Hmm, clearing mobile data by uninstalling Firefox shouldn't affect desktop data. That's very strange.

Can you try using Restore on your laptop? This article has the steps: Restore bookmarks from backup or move them to another computer.

That's what I'm about to try right now. It's strange because there is a bookmark folder but it's dark and when I try to recover from that it just says file not found.

I did go to system restore today and used a restore point from 6 months ago. Still nothing. I'm going to make a Linux boot USB and boot to that. I did it for a couple friends. Gotta get the ios file from Microsoft site. FYI I had a USB with the bookmarks file on it. I uploaded it to my laptop and when I went to import the file just had one of the black gloves looking icons and there was a bookmarks html file but it was empty. If the Linux boot doest do it I'll just get screenshots of all my installation files and save documents and photos to a USB and run malwarebytes on the files as they upload. Rhen do a factory reset from my recovery USB I goth the laptop

I'll let you know how it goes. And thanks so much for your advice on all this.
