Hello,
I've identified a 1-2 seconds jank when I open a page containing a .webm player. This was a trial and error kind of thing but eventually, I realized that was the common pattern among the pages that were giving problems.
I ran the profiler and it's very clearly visible when the problem arises but here my knowledge of Firefox and its tooling falls short and I don't know how to find the root cause of the issue, that probably is not an extension since it appears on different Firefox accounts and in incognito mode.
