Months ago all bookmarks just disappeared. I tried to restore many of the backups but only was informed "Unable to process the backup file." each time. Tried again today with same result. When this first occurred I obtained an article with the steps to solve this problem and did them in order. Reinstall didn't work nor the above. Nothing seemed to work. Note that no new bookmarks then and now can be created. So I have been trying out a new browser which did import Firefox bookmarks - therefore are readable - which placed them on the favorite menu without prompting. These are listed as Firefox Bookmarks. But this is not where new bookmarks are saved. Thus the same topics are in two places. So I attempted to import the Firefox bookmarks manually. It worked but now every folder is on the favorite menu instead of being merged with the new ones created. Of course this is absurd so were deleted. I don't particularly like the new browser and actually would prefer to get Firefox straightened out. I don't recall much about the events when this happened but it did not seem just after an update - possibly a week after? I have four extensions: AdBlocker for Youtube, ClearYRLs, DuckDudckGo, and Norton Safe search. Your wisdom and experience would be appreciated. Ed
