When it's about web development Mozilla's browsers have always been one step ahead. Recently Internet Explorer also added more possibilities for fine tuning of the applications by developers, but they first have to be adopted, because when for long you have been developing a technology aside from the commonly accepted standards then it's hard to make the ones using it to change their way of work. I have always strive to adhere to the commonly accepted standards, so my choice of Firefox as platform for development of web applications is not an accident. In this article, I'd like to present 5 extensions, which in addition to the wonderful browser can make your life easier.
I'd like to make in advance the arrangement that this is not a rating and the ordering is random.
This is one of the extensions, which I'm using the longest. HTTP protocol is of the type request - answer and this extensions allows you to see both. Much useful when tuning applications, because it shows what's transferred and what's received by the browser - headers, cookies, data. With this extensions you could easily find out what server software is serving a given site.
This extension will allow you to check locally your HTML pages with the help of tidy tools of W3C. Through a comfortable user interface in View Source you'll be able to review consecutively the errors and warnings in the source, as well as the warnings for impacted accessibility. Really useful for those that have the willingness to follow the standards.
Although, this extensions comes by default with Firefox I highly recommend it to everyone that for one reason or another do not have it. With this extensions you'll be able to review the hierarchical structure of your HTML/XUL/XML source and to find the elements in the graphical representation of the page. Really useful for reviewing the styles applied to a given element, the size and position of the element and so on.
Those were mine 5 mandatory Firefox extensions for web developers, which I'm using almost every day. They are famous enough, but if you're unfamiliar with any of them then it's time to install and try it. Happy hacking ;-)
