Firefox 33 and javascript rendering problems

[11thHour]

Anyone else have javascript problems with the latest versions of firefox? I've had to revert back to v.25 as many pages just don't render fully anymore (sorry, no examples bookmarked right now.)

That is not a thing.

As for your problem, basic troubleshooting: disable all add-ons and check if the problem disappears. If it does, enable them one by one (or half of them by half of them) to see which add-on is causing problems. If the problem doesn't disappear with all add-ons disabled, then you're gonna need to create a new Firefox profile... Check first though.
