So you can either somehow run firefox with a different class (and match to that), but I don't know how, without using a function from xlib to do that: XSetClassHint(). An it isn't supposed to be used like that.
Indeed -- and this is wrong. Older versions of Firefox used to have a --gtk-class flag which would allow you to change the Class of the window before it is mapped [1] for just this purpose, but it seems to have been removed. [1] The Class of a window is only allowed to be changed in the WithDrawn state, hence why you can't change it with xprop whilst it is mapped. This is in accordance with the ICCCM2. -- Thomas Adam -- "It was the cruelest game I've ever played and it's played inside my head." -- "Hush The Warmth", Gorky's Zygotic Mynci.
