I don't have this problem with my Firefox (v1.0.7 on a Mac), but maybe you should try downloading a new copy of Firefox and see if it works then. I don't know of any settings that would solve this problem. Yahoo! is probably who you want to contact.
I have firefox 1.5 and i am having problems with yahoo! mail's compose part. I was able to do copy paste in the older version of firefox with yahoo compose.
So i try to copy-paste in yahoo! compose, but am unable to do so. I try doing CTRL+V.... does not help either.
Hence i had to download netscape and in netscape8, i could do copy paste in yahoo compose.
Is this a browser problem or some setting i need to turn on in yahoo mail or firefox 1.5??
thanks
