I just got my Mighty Mouse and I love it! One thing that is bothering me though... In Firefox, I like to use the middle click to open links/bookmark icons in the background. I also like to use the middle click to close tabs. However, with the Mighty Mouse I am having trouble getting this functionality to work. I've read that other people have gotten Firefox and their Mighty Mouse to work in the way I described above, but they don't specify how they configured it do make it work. Do you know what Firefox extension I should use to get this middle button functionality to work? Thank you very much for any help.
