Twice in a year, maybe in 2, Firefox updates have completely hosed my bookmarks. I don't always remember to save them when updates come through. This browser updates more than any other one I use. I'm an elder who has to juggle tons of internet details. I can't tell what folder they came from, but there are at least 150 bookmarks skewing the view of my folders. I tried to delete all of them, and if I reopen it, all the ones I deleted are back in the way. Why won't they go away? What is getting confused here? One thing is that I'm afraid Firefox won't reopen all the tabs & windows I have open, so I kill it using my Task Manager, instead of just closing Firefox windows. Why? Because it has lost one of my windows before, with multiple tabs open and I couldn't find any of them. Yes, I'm the one who maintains 3 separate Firefox windows with multiple tabs open. Please do '''not''' tell me not to do that, when I've been doing this for years & years. This thing's limitations shouldn't become mine. Everybody uses products differently; doesn't mean you get to judge when I'm not using it the way you do. I hate that this happens, because I'm not expecting Firefox to make a mess and don't know where they're pulling all these bookmarks from. Nothing is missing from my folders. It's like they're duplicated and show up when I click 'Bookmarks'. They keep reappearing under the 'Bookmarks Menu' with Manage Bookmarks, but obviously not coming from there or they wouldn't reappear when I delete them. Any ideas what's going on? Again, don't tell me how to use my computer. I've been doing this since PC's were invented. If you know what's happening, great. If not, mind your manners & don't let your ego take pot-shots. Thank you.
