User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0 Build ID: 20111104165243 Steps to reproduce: If you are possessing hardware (mouse) with a scroll wheel which also has option for scrolling left & right (e.g. Lenovo Bluetooth Lasermouse) and you are opening a link in a new tab with the middle click, the link will be opend several times (1-4 times) if you are also activating the right/left scroll click of the mouse! It has nothing to do with addons (i tested it with a fresh installed new system as well). The Problem stops, if you deactivate the function for the side-scrolling of the mouse, but then I cant scroll sidewards with my mousewheel any more! Actual results: tab opened several times Expected results: the link should have just opened once, instead of 1-4 times, even when i press the sidewards scrolling button at the same time as well!
Hmm I get the same behaviour but I'd always assumed that the problem was bounce on my mouse. (on Linux, external mouse)
