Sync won't sync on one of my device (win7, ff 41.01)

more options

On the laptop (win7) I use at work sync won't sync. Firefox shows an error at the bottom of the window saying 'Sync has encountert an error during synchronising: Unknown error. Sync will try this action automaticaly again.' (sorry for bad translation from Dutch).

On other devices sync (macbook, desktop win10 & android) works fine. I use sync alot for work and this is unfortunatly bothering me alot. Can anyone help me? I added the sync-error log overview.

Hello,Can you copy error-logs and paste them in https://pastebin.mozilla.org/ or a similar service and paste the link here on the forum?

It may be possible that any "malformed bookmark " cause the problem.You could try is to go to the bookmarks library (ctrl+shift+b) > import & backup and export your bookmarks as .html file and backup as .json once. once you done with this, try to reimport from the backup source again and see if this can address the issue.

However You can also check for problems with the places.sqlite database file in the Firefox profile folder.
