And so we hit a snag.
Our server, Site5, refuses to permit the most secure protocol unless a new hosting plan is purchased. Thus the matter has escalated very much beyond my "pay grade", as they say*. It doesn't all quite make sense to me because we do have some browsers happily performing quite securely.
I will refer everything to Birna and the Crew at this point.
I think you are safe enough entering your passwords under weak encryption. Or set up another browswer for NG temporarily until the matter has been resolved. The safest browser of all is Tor, in case anyone might like to try that.
*Just a little joke about the pay grade. I receive no pay, nor would I want to for those few tasks I perform for NG to help out my friends.
