As a webdesigner (and technologically savvy user of the Internet), there is no excuse for you not to be using Firefox as your primary web browser. If you aren’t using Firefox yet, you need to go and download it right now. Not only does Firefox provide a top of the line Internet browsing experience, but it also provides an endless amount of functionality that you simply won’t find in any other Internet browser.

Because third parties can develop add-ons for Firefox, by downloading the best add-ons that are available, you can transform Firefox into a tool that dramatically increases your productivity and saves you a countless amount of time.?? Since there are so many different add-ons available to download, it can be a little overwhelming to pick out which ones you should be using.

Therefore, I decided to do all of the legwork for you and compile a list of the six best Firefox add-ons for web designers.

1. Web Developer
2. Firebug
3. Colorzilla
4. Fireshot
5. CSS Validator/HTML Validator
6. Browser Window Resizer
