Got tired of waiting, again, and updated iceweasel to 33.0-2 from experimental. So far working flawlessly.
apt-get -t experimental install iceweasel
BTW - I guess I missed the flash update, so, I did that also.
update-flashplugin-nonfree -iv
Thought I'd share.
Even 34.0a2 works fine here in everyday productive work.

Thanks devil, I may give that a try also.
Firefox 36.0a1 & Thunderbird 36.0a1 is also nice and trouble free ;)
