ok since oyu found the path in finder, why dont you just addjust teh link you read in the wiki and make it right?
it does not really matter where the ed2k binary is, it just matters taht you setup the same path in firefox/mozilla where teh binary is in the end
thats all

PS. and why the links dont work, no idear I know they shoudl work....and at least from some other sides they work for me, make sure you just have teh ed2k_part..... and no html tags or something alike
