STR: 1) Login on taskcluster.net 2) Don't use taskcluster.net for a few minutes 3) Try using it again At this point, taskcluster.net shows an infinite "Authentication..." spinner. I have to log off and log in again. I'm on Firefox Nightly on Linux. I'm loading Taskcluster in a "Work" container tab. I'm using the "Firefox Multi-Account Containers" addon (Taskcluster is set to always open in a "Work" container tab).
