Since January 2018, my laptop running Windows 7 (32-bit) has been giving me an error after I close Firefox. I have removed and re-installed Firefox but it still errors. I just found that it is trying to sync and that the last successful sync was on December 31. If I turn off syncing on this device Firefox closes without any error.
