I using this code.
Code:
on $^*:HOTLINK:/^\W*(((?:https?|ftps?):\/\/|www\.)\S+)\b/:*:return
on $*:HOTLINK:/^\W*(((?:https?|ftps?):\/\/|www\.)\S+)\b/:*:runmax firefox.exe -new-tab $regml(1)

And never failed me so far, easy to use, just paste the code in a remote file.

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
