Since around noon on December 12th none of my firefox addons can sync the vault. Inspecting the addon there are no bad network requests, it seems like the data is even being sent from the servers, and there are no printed error messages. All I get is the “Syncing Failed” toast and no more info.
I have checked to make sure the addon is up to date, I have restarted firefox completely, I have inspected the addons network and console info. Is there anything else I can do to try and figure out what the problem is so I can fix it?
