Error when logging in to Firefox Monitor "You must be signed in to your Firefox Account."
When attempting to login to my firefox account in the firefox monitor page https://monitor.firefox.com/ I enter the correct credentials and am prompted with "You must be signed in to your Firefox Account."
Tried deleting cookies, cache and browser data, private window, restarted the pc in safe mode, disabled all add-ons, disabled all firewalls and/or antivirus software. Nothing worked.
I have reported the bug here: https://bugzilla.mozilla.org/show_bug.cgi?id=1559901
Any ideas how to solve this, as I'm receiving a hundreds of notifications on an email I am monitoring and no way of turning off or removing that email from the list.
