So, this is what i was afraid of, except it's not a plugin, it's a NSS
module that you installed. You'll have to figure out why it freezes.

At best, iceweasel could (should) initialize the nss modules off the
main thread to avoid freezing like this, but this is not a serious issue
anymore.

What you can do is install the libnss3-tools package, and disable the
faulty NSS module with modutil -dbdir ~/.mozilla/firefox/$profiledir
-delete or -disable (-list will give you a list of the installed
modules)
