Firefox freezes after starting recording profile

I am trying to use the profiler. I have added the button as stated in https://profiler.firefox.com/, but when I hit Start Recording Firefox completely freezes and I have to quit it. My OS is Ubuntu 20.04. I have tried with version 91 in a virtual machine and it works fine. Have also tried with version 93 in a virtual machine with Fedora 35 and even though it lets me start recording, the moment I hit stop it freezes.

I filed an issue in the Firefox Profiler GitHub and they were very helpful. Apparently it is an known bug, they offered a provisional solution in the issue linked, in case anybody runs into the same problem.

I had the same problem with 98.0.1 (Linux). I have removed the toolbar button and won't go near the app again.
