    I’d recommend becoming super familiar with chrome/webkits’ developer tools too.

    if you set

    chrome://flags/#enable-devtools-experiments and


    to true and add tools for debugging the major javascript frameworks – Rect = Rect Dev, Angular = Augury, Vue.js = vuejs devtools etc; – and you can understand javascript the concept of the dom and shadow dom, HTML, CSS and take a look at OWASPs’ top 10 you can get 99% of the work done that would otherwise need lots and lots of frameworks and extensions.

    At the time of writing I think Firefox-Dev/Nightlies version – including servo is written in rust – is better than chromes own implementation but each to their own!
