We just looked at this bug as part of our breakage triage. We can't reproduce, does it still reproduce for you? We suspected it could be related to our cookie banner handling feature, but that's disabled by default in normal browsing in both Nightly and Release.
If you can still reproduce, could you share the performance profile you recorded in the video? Maybe that can give us some insight into the bug.

This website was also reported in the Firefox support last week for freezing the browser with Firefox 107 and enabled ETP and I was able to reproduce. I tested again and I am no longer able to reproduce. I will also ask the reporter in the support forum for confirmation.

I will also ask the reporter in the support forum for confirmation.

The user confirmed that it's fixed for him as well.

I confirm, the issue is no longer reproducible with the latest Nightly version.
