Just an FYI. I got tired of waiting for iceweasel and icedove 32 to move from experimental to unstable, so I pulled them both from experimental, and, both seem to be working just fine.
apt-get -t experimental install <packagename>
Right -- yesterday I started to install the iceweasel version in sid, and it popped up several "grave" bugs. So, I decided if I'm going to install it with bugs, might was well get the latest from experimental. It also warned of the same bugs, but I have not had any issues using it for 24 hours.
I'm using IW 34.0 from Mozilla Debian repo (Aurora). It's working fine. I did have issues with 32 from Aurora but these seem fixed in 34.
Love nightly for long time :)
