Comment 67 for bug 38131

Of course there's a difference, ryanmbruce.

The thing is that both Xorg and firefox CPU usage dramatically rise when i go to some sites, and it stays this way even after the webpage finishes to load.
For example, while being in this site and writing this post, both firefox and Xorg CPU usage is below 1%.

When i go to http://www.keshet-tv.com/nehederet/ , firefox CPU usage rises to more than 85%, and Xorg usage rises to ~10% and it stays this way even after the page finishes to load. (actually it stays this way until i leave the webpage) . Keep in mind that each one of them was below 1%.

I guess Xorg and firefox CPU usage are somehow related, especially when there are sites loaded with javascript/videos.

Try going to the mentioned site yourself and check your CPU usage.

I agree that maybe this bug should also be opened in bugzilla.mozilla, i'll check if theres's an open bug.

Thanks,

Joel
