Sorry I wasn't running a shark build. This seems to have started just since my last nightly update. I'm at

http://hg.mozilla.org/mozilla-central/rev/bd55083cbaaa

Anyone else seeing this? At least it's not Flash this time (I'm still having bad hangs due to Flash 10r12 -- happend with r22 as well before I went back -- in both Firefox and Safari; any clues there would be appreciated).

Hovering around 60% still, nothing going on in background tabs as far as I can tell. Gonna have to restart.

¡Hola Brendan!

Is this still an issue on a current Firefox Nightly install, please?

You can get the Firefox Nightly installer from https://nightly.mozilla.org/

¡Gracias!
