Mr. E.P. It was late last night, and I probably should have double checked my facts. There has been talk of porting Konguerer to run on the gecko engine. http://dot.kde.org/1094924433
When I go to ipchicken.com in Konquerer it does say "...khtml, like gecko...", so maybe there is/has been some work on that project. Sorry for spreading any mis-information.
BTW, I'm looking at this in FF on SuSE 9.2, and my fonts look fine, a little bolder than in Windows FF, but not that different.
