In addition to the GTK2 stuff firefox used which is related to this bug, there is some xlib stuff firefox uses which will still be a problem as a wayland client after this bug is closed.

There is another bug specifically for wayland support: https://bugzilla.mozilla.org/show_bug.cgi?id=635134
It hasn't gotten much love.


There is also their new servo engine, which also has a bug for wayland support, but that seems pretty far off from being usable: https://github.com/mozilla/servo/issues/332
