Posting Hotlinks in Yahoo mail w/Firefox?

i believe there is a thread on this here somewhere and i think i started it, but got tired of searching. anyway, i'm still having problems posting hotlinks in yahoo mail using firefox. what i'm talking about is when u have ur yahoo email open and u wanna send a url to someone via email i copy & paste. when i do that with firefox the person receiving this email has to copy & paste the link i sent to the address bar in order to visit said site. the person can't simply click on the link to go there. how can i fix this?
