These tools cover all the basic needs for inspecting, debugging, and optimizing websites, just like any Chromium-based developer console. I use them daily to edit HTML and CSS live, monitor network activity, profile performance, and test responsiveness across devices. The interface is clean and the features are reliable, making it easy to analyze page structure and troubleshoot issues on the fly. Review collected by and hosted on G2.com.

As far as for essentials, Firefox Developer Tools always deliver. Review collected by and hosted on G2.com.

I like how Firefox Developer Tools assisted in the development of my website geekskai.com by providing a lot of resources and tips to guide me through the process. I appreciate the layout and CSS tools, particularly how visual the layout tools are and how direct the CSS editing workflow feels. Additionally, the initial setup was very easy.

Two areas feel weaker than the strengths: performance/robustness on heavy apps, and some gaps in debugging and UX polish compared to Chrome. Review collected by and hosted on G2.com.

Good amount of memory is used by the browser instance, should be using much less memory than it uses today. Review collected by and hosted on G2.com.

I started using browser-based developer tools with Firebug back in the day and then eventually cut over to use Chrome tools. However, after Firefox came out with its focus on privacy, I started using it again. And I'm happy to say that it's at parity with Chrome in this area. Review collected by and hosted on G2.com.

The new interface. Mozilla connects a home run with the new Firefox Developers Edition, which includes the full-featured Firefox Developers tools. The Dark theme does not tire your eyes when you're spending a lot of time debugging your app. In addition, it has a lot of improved features, such as the style editor, the responsive view, and the new option of Valence add-on, which allows you to connect the Firefox developer tools to other browsers (for example Safari on iOS) Review collected by and hosted on G2.com.

Every developer or QA should get this tool. It is really life saving for all developers. I am a backend developer but this tool provides me a way to debug and look JavaScript in the browser without pulling my hair out. Not only devs and QA but I had support staff, they used this tool to find some of the data from front end. I debug my JS or angular. You can inspect element and can know current html. I favorite one is you can see the actual method code in the browser. Review collected by and hosted on G2.com.
