Updated to 6.0.1 a few days ago and now the hanging and freezing are even worse. Also has crashed about 20 times, always when loading a new tab, often on pages with Flash (which is up to date). Many pages take forever to load, don't ever load, or partially load with images missing - and the activity indicator circle just spins and spins. This is really driving me crazy. Don't know whether to look forward to Ff7 or dread it. Unfortunately have to use Ff for work.

Holy hell, I am about to give up on this version of Firefox.

You have to be TRYING to screw up this much.

I'm going back to v3. Let me know when this crap blows over and all Add-ons have caught up with these excessively released versions(you idiots updated it over three times last month, no wonder none of the freaking Extensions work properly) that don't work for much more than a headache.

Just updated to Ff 7 and same thing! Pages that do load, load much faster, but 1/4 to 1/3 of pages take forever, some don't load at all. Pages have place markers in place of some images. Also, the memory problem is no better. Gets up to over a Gig after a few hours. Unbelievable.

Finally solved. See https://support.mozilla.com/en-US/questions/880685
