Actual:
On Firefox the responsiveness is very slow. We sometimes wait a couple of second before having something moving on the screen and then a couple more seconds to get the image.

A profile taken on Firefox on an Android device.

I don't see anything DOM Events specific in the profile. Lots of JS and some weird allocation under document.cookie setter and such.
