Hi royg21,

Thanks for the report, however development and bug tracking for the Containers add-on is currently being tracked in GitHub (https://github.com/mozilla/multi-account-containers). I've logged your issue there https://github.com/mozilla/multi-account-containers/issues/1191.

Could you please add a performance profile in the github issue using the https://perf-html.io addon? 

Considering this I will close this issue in favor of the github one.
