Shoutbox

Hey everyone, i know this has been asked before and yes i used the search function to come up with this thread http://shoutbox.menthix.net/showthread.php?tid=34...d=337910#pid337910
However the question was never answered.
My question is when clicking on links inside my tabs such as msgplus and neowin the pages still open up in IE even though i know firefox is my default browser. When i open html pages they are brought up in firefox. the same as when i click on other links.
I also use stuffplug to open hotmail in my default browser and that works fine.
So please if anyone has an answer to this or could point me to somewhere that does that would be great.
Thanks
