There appears to be a whole bunch of CPU usage because of image hosts. Presumably this is because of YouTube, the URLs are stripped in this profile but I'm assuming that's the main page.

I don't think playing a video should ever be causing this type of CPU usage though. Markus do you see anything actionable in here? Otherwise we should probably close out if the reporter isn't responding. The anonymized profile makes it difficult to say anything meaningful about how this is being triggered.

We seem to be full-tilt compositing. I think this means that layout.frame_rate was set to zero. dainguhn1999, can you check if you had that pref set? Please reset it to the default of -1.
