Lately I've been having trouble with keeping deleted bookmarks and folders in my bookmarks toolbar from reappearing. The folders in particular have been persistently returning just a minute or two after deleting them. It's also quite noticeable when they come back as I have the 'show bookmarks toolbar' option enabled by default. I've restarted my firefox browser, uninstalled+reinstalled and refreshed and the problem continues to happen. Before trying those methods I tried clearing cache and cookies in settings with no luck either. From what I've noticed it appears to be just a certain set of bookmarks folders which I don't even recall ever adding to the toolbar; some of them look like they are from other device bookmarks I added after syncing. The rest of my bookmarks library seem to working fine however. I looked over the Firefox support articles on the subject as well but couldn't find a fix. Does anyone know something else I could try?

Any help with resolving this annoying occurence would be much appreciated!
