Firefox 3 X Window Class

If there’s a easier way to figure out the class of a running X window,
I’d like to know how to do it…

xprop WM_CLASS

@damtor

Without getting the firefox version 3 source and recompiling it, I’m hoping
someone has an idea as to how I can change the X window class for a Firefox
version 3 window.

You can’t. Earlier versions of FF used to allow you to do this via GTK, but not anymore it seems. Note that the application itself is only allowed to change the class – and it isn’t allowed to be changed post window mapping.

@damtor

Alternatively, if there’s some other way to accomplish my goal of having the ability to force Firefox to start in a particular window when fvwm2 is started, but start in whatever window
I’m in on later invocations, , I’d be happy to try that as well.

Style Navigator StartsOnPage foo

DestroyModuleConfig a:*
*a: add_window SomeFunc

AddToFunc StartFunction I Module FvwmEvent a

DestroyFunc SomeFunc
AddToFunc   SomeFunc
+ I ThisWindow (!Navigator) Break
+ I Any (Navigator) Style ....
