ControlClick in Firefox even possible?

[darkmaster071]

ControlClick("Google - Mozilla Firefox", "", "[CLASS:MozillaWindowClass; INSTANCE:2]", "left", 1, 543, 763)

I want to send control clicks to firefox window, but often firefox randomly changes its INSTANCE in control Class. Once its [CLASS:MozillaWindowClass; INSTANCE:2], next run is [CLASS:MozillaWindowClass; INSTANCE:6], then instance 5...... I tried WinGetClassList(); but it gave me nothing usefull. I also tried using functions from FF.au3 and MozRepl but the images-buttons im trying to click are tied to javascript code and i havent had luck even identifying them... Help greatly appreciated.
