I would prefer to minimize the browser window by double-clicking next to the open tab (and don't really have a use for tabs, anyway). However, with the way it's set up currently, I have to be very careful when double-clicking the window, making sure the curser clicks above the tab area or it will add a new tab instead of minimizing. I cannot seem to turn off this functionality in any of my preferences or toolbar options and do not have administrative rights to upgrade to the newest version of Firefox. Is there a command I can type into the location bar to hide or disable this?
