I've followed the directions I've found in looking for answers to this, and they haven't worked. My bookmarks haven't appeared when I switched between 2 profiles and nothing has appeared when I went to the Library and tried the various restoration options. I also can't bookmark any webpages since I've lost my bookmarks. I'm using this in Windows 11. Ccleaner found 19 GB of system files that it didn't name, and it wouldn't delete them, so the bookmarks may still be there - I just don't know how to find them. Thanks for your help.
