Description Timothy Nikkel (:tnikkel) 2012-08-14 12:00:34 PDT
Hold ctrl and rotate the mouse wheel to change zoom. Change tabs. Return on the original tab. The zoom change is lost for me.

I bisected this down to the patches for bug 719320.

It is necessary to adapt preferences name to the latest.

Ah, failed to catch such code by searching "mousewheel.".

Hmm, this feature doesn't work with SpecialPowers.setFullZoom(). I think that when zoom in or out is performed, Gecko should dispatch a custom event and browser should listen it. But this patch is enough for now.
