The next extensions are great for web developers.

  • Firebug (www.getfirebug.com)
    A very useful tool for developers. With this tool it’s quite easy to find errors in Javascript, is it possible to optimize your CSS, find objects, etc. Hint: Disable Firebug for alle websites, except for development.
  • HTML Validator (users.skynet.be/mgueury/mozilla)
    Do you write (X)HTML correctly? With this tool, everything is inspected. You learn writing your code and every browser will understand your site.
  • IE Tab (ietab.mozdev.org)
    Every developer’s nightmare: Internet Explorer. Luckily there are tools to view how Internet Explorer interperts your code. With this tool it’s very easy to switch between both engines – in the same tab.
  • Web Developer (chrispederick.com/work/webdeveloper)
    This extension does almost everything you might need. Look at the website for more information, but I use it regulary and the tool might also come in handy for ‘hackers’.
