I keep on getting the following error message: "Sync encountered an error while syncing. Unknown error. Sync will automatically retry this action." Also, at this time, my bookmarks are useless: I lost all my bookmarks and I cannot add any new ones.

Chosen solution

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.
