Derived from comment 67 of bug 61684. When you view the page, it loads or reloads quickly. If you ctrl-+ a few times and reload, it locks up. You may get some unresponsive script warnings. I haven't figured out all the ways it fails, but those basic steps have knocked out a current Aurora build and a nightly from last week. Just guessing at Layout or Reflow; if I was at home on Linux I'd run it under jprof, which can get a profile even if you lockup or crash. It may be an O(n^2) or worse that only raises it's head on zoom, and so may be a general perf bug, not a lockup bug per se.
