This sounded like a great tool, but unfortunately, one feature I was excited about, the Cookies Editor, does not work well. For some reason, when I have it display what cookies are on a page, it only displays some of them. If I go to Chrome Developer Tools, I can see them all.

Additionally, I found the Device Simulation a little clunkier than what I currently use, which is Hoverify. Hoverify allows me to launch directly from the browser instead of having to open another application.
