I have a logitech mouse that has an extra button. I have asigned this button to close the active window/software or a single firefox tab. However, when I try to usethis mouse option to close the Firefox Download Window it does not work. I would like to know if the download tab is an add on or a .exe file in firefox. If it is a .exe file I can enter the software information to my mouse software thus the mouse button can work to close this Donwload window. logitech mouse mx440 windows 7 firefox 4.0 /o/ Thanks for your time.
