You can disable this in FireFox by using about:config to set nglayout.enable_drag_images to False. This will force FireFox not to create a little image of highlighted text when you drag it, and will no longer cause KWIN to freak out and disable compositing. The fact that you're dragging will be represented by a little icon rather than a picture of what is being dragged.
