Instead of trying to perform major surgery on this thread, perhaps we could have a subforum dedicated to Mozilla Firefox and other browsers derived from it. This thread, and the link to it, would then remain the same as now, so the links in NM 28 and Serpent 52 wouldn't be broken; it would just be the first pinned topic in the new subforum.
Folks could then create other threads in that subforum to discuss issues with "official" FF, Seamonkey, @roytam1's builds, etc., thus reducing the "clutter" in this thread going forward. (Sometimes folks do that now, but the thread winds up in the larger XP forum, so it can quickly get lost among all the other XP topics being discussed.)
