Top 21 Firefox Addon every software engineers must know

Mozilla Firefox is a very popular browser, especially among web designers and developers. These days, with such a crowded field, staying at the top of the browser heap takes a lot of work. One of the factors that make Firefox so well-liked is the huge library of great extensions that enhance your browsing experience.

Among the massive list of add-ons, many are vital to web designers and developers. If used, it will make your workflow quicker and more productive. Let’s look at our top 21 essential Firefox extensions for web designers.

1. Web Developer

I absolutely recommend the ‘Web Developer‘ add-on. It gives you some great features which will make your development workflow faster. I enjoy various CSS, form, and image options. No matter if I want to check alt tags, missing images, or image dimensions, this add-on is my preferred choice.

History & Origin of Web Development

Where the Web was born. Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.

CERN is not an isolated laboratory, but rather the focal point for an extensive community that includes more than 17 000 scientists from over 100 countries. Although they typically spend some time on the CERN site, the scientists usually work at universities and national laboratories in their home countries. Reliable communication tools are therefore essential.

The basic idea of the WWW was to merge the evolving technologies of computers, data networks and hypertext into a powerful and easy to use global information system.

How the Web began

Tim Berners-Lee wrote the first proposal for the World Wide Web in March 1989 and his second proposal in May 1990. Together with Belgian systems engineer Robert Cailliau, this was formalised as a management proposal in November 1990. This outlin

ed the principal concepts and it defined important terms behind the Web. The document described a “hypertext project” called “WorldWideWeb” in which a “web” of “hypertext documents” could be viewed by “browsers”.

By the end of 1990, Tim Berners-Lee had the first Web server and browser up and running at CERN, demonstrating his ideas. He developed the code for his Web server on a NeXT computer. To prevent it being accidentally switched off, the computer had a hand-written label in red ink: “This machine is a server. DO NOT POWER IT DOWN!!

2.User Agent Switcher

The User Agent Switcher allows you to switch the user agent of your browser. The add-on will add an option to the tool settings. This option lets you switch the user agent.

 

The User-Agent Switcher allows you to switch the user agent of your browser. The add-on will add an option to the tool settings. This option lets you switch the user agent.

The Basics

When your browser connects to a website, it includes a User-Agent field in its HTTP header. The contents of the user agent field vary from browser to browser. Each browser has its own, distinctive user agent. Essentially, a user agent is a way for a browser to say “Hi, I’m Mozilla Firefox on Windows” or “Hi, I’m Safari on an iPhone” to a web server.

The web server can use this information to serve different web pages to different web browsers and different operating systems. For example, a website could send mobile pages to mobile browsers, modern pages to modern browsers, and a “please upgrade your browser” message to Internet Explorer 6.
