:yoasif, if you think that's a regression, then could you try to find a regression range in using for example mozregression?

Is it janky after the page has completely loaded? It's not for me.

It is much less janky, but I see a lot of slow frames:

Hey Asif,

One thing we noticed while looking at your profile is that there's another process that's loaded dawnnews.tv, which is loading instagram stuff, which embeds dawnnews, which kind of does this whole thing recursively, and it's really bogging down that one content process and also causing the UI to do a lot of work to respond to all of those loads (since networking happens in the parent process).

Do you still experience this issue if dawnnews.tv is not running in the background?

Mike, it still feels pretty janky -- new profile from today's nightly: https://perfht.ml/34hyRiD

Seems to run well now.
