In recent years Mozilla Firefox has seen a rise in popularity as a safe, lightweight, and fast alternative to Google Chrome. With its robust but also stylish build, Firefox offers a lot of customizability that both the average user and a seasoned web developer can appreciate, especially if one is willing to get their hands dirty.

Developed with web design in mind, Firefox comes with basic web design tools that one expects from any decent web browser. And while the built-in HTML/JavaScript/CSS editor, examiner, and debugger are great, they are only enough for a person to develop a functioning albeit bland website.

Along with this, Firefox also has built-in performance tools, an accessibility inspector, and a responsive design mode. But what if you need more tools? Well, thankfully, Firefox has got you covered.

With more than two thousand Firefox extensions that can be installed with just one click, the chances of you not finding the tool that perfectly suits your needs are quite slim. All of these extensions modify your browser in small but significant ways. Having said all that, the number of choices you have can be quite daunting.

So, to help you have an easier time making your pick, this article will list some of the best Firefox extensions that you can find. Without further ado, here they are!
