Countless times I have read Teodor write “what does the console say?” and I wonder if it is because many do not know how to use it, are afraid to open it or just do not want to have anything to do with it.
For a developer the web browser console is as important as for a doctor to ask his patient what is wrong or examine him.
I’m not saying that all, but 60% -80% of errors can be corrected faster if we look not only at the console but also at the many tools that modern browsers give us.
The developer tools can help to improve the performance, code and aesthetics of our website or web application.
So I bring you this video that summarizes many tools that perhaps some of you do not use and can help you work better.
I have used Firefox for many years but now I have returned for a convenience to using chrome, so I share with you a few additional tools that I use:
Colorzilla
GoFullPage
WhatFont
Wappalyzer
DarkReader
GitPod
If you use other tools, please feel free to share them 
And always remember
