MozBar not working today

As of today the MozBar doesn't seem to work at all and no regular solutions fix the problem. Tried clearing all browser data, restarting, logging in from a different account, different PC but nothing works. The toolbar always asks me to login no matter what I do.

Does anyone else have this problem and do you know what's causing it or how to fix it?

Do you use Moz bar? Do people still use that tool?
