It's being worked on, I let the staff know.
Meanwhile, here's what I've found:
Chrome and MS Edge are whining about the current SSL version being used and you'll have to jump through hoops every time you want to read a post on the GDB.
SeaMonkey Suite, which is an upgraded version of the old dinosaur Netscape Navigator, will whine, but allow you to make an exception whether temporarily or permanently. If you make a temporary exception you'll be in the same boat as if you used the other two browsers. If you make a permanent exception it'll reconfigure and allow you to browse freely as always.
