Details

Whenever I look at a page that includes the Octoprintthe webcam view, the web content in that tab becomes nearly completely unresponsive (and the webcam image doesn't update as it should). This works fine in Chromium.

I'm on Nightly with build id 20210529092554.

I took a profile using the "Web Developer" preset: https://share.firefox.dev/3vzXaFC. It shows a lot of jank, and it seems to be doing a lot work related to HttpChannelChild::DoOnDataAvailable.

I don't know an easy way to reproduce this elsewhere, but I can reproduce it reliably here. I'd be happy to try any debugging steps that would be helpful, or I could try and get someone remote access.

I haven't seen this in a long time, so I assume it was something transient or local.
