I can't add or remove bookmarks from the bookmarks menu or bookmarks bar and I've completely removed and reinstalled Firefox.
I am not able to add or remove bookmarks. The bookmarks library is empty. I can't restore to any back up bookmarks. I restarted in safe mode. No bookmarks. I reset Firefox. No bookmarks. I uninstalled and reinstalled Firefox. No bookmarks. I did a Revo Uninstall and cleared the registry. No bookmarks. I deleted the localstore.rdf. No bookmarks. This is kinda a deal breaker for me. I might have to go to Chrome or IE.
Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
