From the log, I can only tell that most of Http requests are canceled right after nsChannelClassifier is created.
Please see an example below.

Set this to P3 for now, since we don't have enough information to proceed. The log only shows that a lot of http requests are canceled for some reasons. This could be caused by an addon or a service worker. It's difficult to tell.
Feel free to raise the priority if you have the STR. Thanks.
