soz if this is already posted.. ive searched the forums, but, i think a cool script would be one that opens links in a firefox browser or gives you a choice of the browsers.. for example: emails wouldnt open in IE but in Firefox..

Thanks

Searching, I came across this script which is good.
Note: It's a script, not a plug-in, therefore required WLM and Messenger Plus! Live

But it has been asked many times before. Read for more info:
