A while ago I wrote about some of the extensions I use with Firefox which make the job of web development easier. I've since added some new ones to Firefox that I use on a fairly regular basis, so thought I should update the list.
As mentioned previously, I have a personal favourite browser when it comes to web development and that is Firefox. This is not only because of its good standards support (although it doesn't yet pass the Acid 2 Test) and not because it has tabbed browsing and not because it's any other browser other than Internet Explorer.
