When you create a template, one of the important evidence to overcome is that our design will look good in most of the possible resolutions. There are several options to achieve this, from different applications to get help from our friends, but one that I found interesting is the extension for Firefox Window Resizer.

Window Resizer allows us to test our design in various resolutions by changing your browser in our time to test it. Supports 640×640, 800×600, 1024×768, 1280×1024 and 1600×1200. We can do this through a context menu, the toolbar or a button on the top of your browser.
