One of the great things about Firefox is XUL and the ability to write extensions with a relatively small amount of effort – this is not the case with Microsoft’s IE. Anyway, two really cool extensions that I just found are: IE tab, which allows you to switch browser engines from within Firefox and Notefish (an extension is also available for IE). Notefish is a tool which I’ve been wanting for a long time and now it here – try it and use it! For more extensions, checkout the Mozilla site. If you don’t have Firefox – get a copy here.
