Great extension! but I need the ability to resize my browser window to mobile browser sizes, there's only the options 800x600 (which nobody uses) and 1024x768. Please can you add 320x480, 480x800 and 640x960 - either that or the ability to define your own screen size?

Not as feature packed or as useful as the Firefox version, but still a decent tool for any web developer. Recommended.
