While Mozilla puts together a fix for the issue, they have paused Firefox updates. When the bugs are squashed and a patch is ready, updates will resume. So just be patient for now and things should be back to normal in due course.

I think I’m finally switching back to FF from Chrome because Chromes memory usage and handling is pathetic in comparison.
