Whether you are a web developer coming to Firefox from Internet Explorer or another browser, or you’re just starting out and want to get all the plug-in based help for Firefox that you can find, take a look at this excellent list of helpful plug-ins for Firefox to help you get the job done. We haven’t done any pointer posts to big lists of high-quality Firefox add-ons in quite a while; in my opinion it’s worth taking an hour out and looking through a comprehensive listing  like this because I don’t think there’s any doubt that habitually making use of Firefox plug-ins rather than standalone applications is a great way to accelerate your workflow.
