this actually *is* bug 50836.
there is a little explanation there (getCSS() is called from "load", but the
results are not cached, as you and Bartos noted), and an untested patch that
fixes the issue.
if the people who reported the "freeze" can confirm they see high cpu usage
during the time the browser is frozen, i think it would mean that you were
right, and the two reports are actually duplicates.
Either way, the profiling information definitely fits bug 50836 .
peace.
