Unfortatelly not. I asked this:
in another topic as well, but it looks like that nobody (at least here in the Forum) has an answer yet.
I would like to encrypt my FP2 as well again (see the last few entries in this topic, beginning with the linked one), but I’m not sure if it is a good idea to use SnooperStopper again.
In an XMPP MUC some FP2 owners said that they don’t have any problem while using SnooperStopper. I will asked there again and post it here if I get any relevant info.
