It looks like aPrincipal is null in PrincipalToPrincipalInfo.

The crash volume looks low, but I was able to reproduce this crash immediately by visiting the URL https://company.italki.com/careers

Though the volume is very low, it seems there are different ways to arrive at PrincipalToPrincipalInfo that manifest this crash.

Andrew, does this still reproduce for you?

No, it did not reproduce for me. That was a URL I found from a crash report. I did notice another crash report from Firefox 97 that also had that URL, so maybe that particular crash was fixed between 97 and 99.
