I've been unable to use Firefox Sync on my main PC for the better part of a week now. As stated in the title, I've already run the Places Maintenance add-on, but that has yielded no results. The computer was shut down abruptly due to a power outage just before this issue started, though no other programs seem to have been effected by that.

This is the log of the last time I attempted to sync: https://pastebin.mozilla.org/8849924

Delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). Remove an existing chrome://FirefoxAccounts entry in the Firefox Password Manager. If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

You can use this button to go to the current Firefox profile folder:

Can you log in to the Sync account via this page?

I just uninstalled Firefox and deleted both Mozilla folders in AppData (one in Roaming and one in Local) and that fixed it. For whatever reason, your suggested solutions had no effect, and neither did resetting Firefox. Thank you for your help, though! If there's a log file or similar I can post that would help diagnose future problems like this, I'd be glad to provide it.
