Details

Opening a youtube video that supports HTML5 is freezing Firefox for me for a few seconds, triggering an unresponsive script dialog, and then freezing for a few more seconds after closing the dialog, and then resuming normal operation.

I tried to profile this using BenWa's profiler, and js::ShapeTable::search and array_toString_sub shows up, so that's why I'm filing this in the JS engine. Apologies if it turns out to be something else (or just that youtube is doing something wrong).

CC'ing BenWa as he might be able to see more useful information from the profile:
