Looking at the console I see often output like ``` [03-15 07:54:18] Torbutton INFO: tor SOCKS: https://www.torproject.org/projects/torbrowser/RecommendedTBBVersions via :dceca4bdbd10c5b87865edd4fac205eb [03-15 07:54:18] Torbutton INFO: Failed to get credentials or browser from channel ``` It seems this is caused by `isolateCircuitsByDomain()` not throwing anymore if there is no domain to isolate the request to. We should take care of that as that probably breaks our catch-all circuit handling.
