Hi, When working in responsive design mode, using javascript alert() doesn't do anything. This is really frustrating for debugging and sometimes I think that the page is cached or something else is wrong before I remember alerts just do not work in responsive design mode. So now everytime I test my sites for mobile I use chrome, which sucks because I hate chrome and want to use firefox. What is the reasoning behind this? I'm sure alerts work on mobile, so why when im emulating mobile will they not work. Please can we get this added into firefox. Thanks, Trent
