Mozilla Firefox has become the most powerful, renowned and a web browser used by millions across the world. Each and every internet user uses a web browser to surf on internet. But when it comes to web development, web browsers are crucial for the guys in web development process. They have to keep an eye on all web browsers to check if there’s any web displaying problem with their website while using a browser. Being a graphics designer and web developer, dealing with these web browsers to ensure the right arrangement and error free website has become my routine.

Searching for errors and optimizing your pages is a real pain and time consuming. But now for Firefox there are tons of add-ons that makes web developers’ life much easier. During my whole career I came to many Firefox add-ons, I used them, removed the less productive ones and kept the most powerful Firefox add-ons. In this post, I am going to share, with you guys, all those Firefox add-ons that make a web developer’s life a real ease. These add-ons or extensions are also called in-browser tools.

Below is the list of Best Firefox Add-ons for Web Developers:

“Performance and network tweaks for Firefox.

Fasterfox allows you to tweak many network and rendering settings such as simultaneous connections, pipelining, cache, DNS cache, and initial paint delay.

Dynamic speed increases can be obtained with the unique prefetching mechanism, which recycles idle bandwidth by silently loading and caching all of the links on the page you are browsing.”

FireShot is a Firefox extension that creates screenshots of web pages.

Unlike other extensions, this plugin provides a set of editing and annotation tools, which let users quickly modify web captures and insert text annotations and graphical annotations. Such functionality will be especially useful for web designers, testers and content reviewers.

It’s possible to choose whether you want to capture entire web page or take screenshot of only visible part of the web page.

The captures can be:

  • uploaded to FREE public screenshot hosting
  • saved to disk (PNG, GIF, JPEG, BMP)
  • printed
  • copied to clipboard
  • e-mailed
  • sent to configurable external editor for further processing.”

“Winner of the “2006 PC World World Class Award”, NoScript tool provides extra protection to your Firefox. It allows JavaScript, Java and other executable content to run only from trusted domains of your choice, e.g. your home-banking web site, guarding your “trust boundaries” against cross-site scripting attacks (XSS) and Clickjacking attempts, thanks to its unique ClearClick technology.

Such a preemptive approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality…

Experts do agree: Firefox is really safer with NoScript ;-)”
