Firefox has been updated to version 8.0.1. Try updating Firefox and see if that solves your problem.

For a clean installation,

• download the new version,
• uninstall the old version,
• delete the Firefox program files folder, then
• install the new version with administrator privileges.

i have downloaded version 8 of firefox after deleting earlier version.The problem is no more .thanks for the help

I have already updated to 9.0.1 and I still cannot attach anything to an email. I did not have this problem with earlier version of Firefox. What did you do to the system? This is very annoying.

You guys are not going to believe this I figured out the problem it's really dumb...ok here goes the attachment uploader loads seperate so I got to thinking it's a popup so I went to options content and under block pop ups there is an option exceptions click on that and in the box type www.firefox.com and hit allow pow its fixed!!!!! :-)
