Information to all...
Iceweasel Aurora 30 has been released and VSIDO users who are up to date with dist-upgrades will get the new update
The issue is nothing will save and no settings will load. This is a known bug and should be corrected very soon but in the mean time you may want to consider putting a hold on Iceweasel version 29. You can do this like so
sudo apt-mark hold iceweasel
When the error is corrected you can unhold it like so
sudo apt-mark unhold iceweasel
One could also edit /etc/apt/sources.list and comment out
deb http://mozilla.debian.net/ experimental iceweasel-aurora
for the same results
I just dloaded the nightly build of Firefox and ran it ... 31.0a1 (2014-03-24) ...
Everything has been fixed and it is running perfectly. Users just need to wait for the packing to make it to the debian servers/repos. I think that will happen in a couple of days
Iceweasel (30.0a2 (2014-03-28)) was finally updated in SID today and this issue is now resolved
Nightly Firefox is still a great choice and fun to run and see daily changes
