08. GridFox

One of the most frustrating issues that a web designer undoubtedly encounter when coding grid-based layouts. How can a designer be sure that the grid is maintained from the original mockup to the final coded version?

10. Browser Window Resizer

The Browser Window Resizer is useful tool for testing different screen sizes. It accurately resizes your browser so you can test to see if the web page you’re working on looks right in all of the standard resolution sizes. This will allow you to see if your design is going to look good to visitors who aren’t using the same resolution as you. The best thing about this add-on is that if you are using it in conjunction with the other add-ons in this list (specifically Firebug), when you see that something isn’t displaying properly, you can instantly make adjustments to your code and see if that fixes the problem, all without ever leaving your current browser window.
