As I mentioned in the previous post, I have switched to using Firefox as my default Browser, which I was able to do this largely thanks to the great IE Tab extension that allows me easy access to Internet Explorer, from within Firefox, for testing and compatibility purposes.
Now, I've been a Firefox user in a secondary sense for a couple of years, since long before version 1.0, and in that time I have come across som pretty good (even great) extensions such as the indispensible Web Developer toolbar, as well as some utter crap, and I got to wondering what else might be worth a try.
Obviously I don't want to go as far as this clown, but there must be more useful extensions out there and so I thought I'd see if anyone had any suggestions? What extensions do YOU use?
