Firefox extensions. Geddit? (Whistling wind, tumbleweed.)

Suit yourselves.

Anyway, Gordon mentions some of his favourite extensions. The Web Developer extension in particular is a must-have. If, that is, you are a web developer. ;-)

There are a few extensions that I'd hate to be without that he doesn't mention:

• Linky allows you to drag-select a bunch of links and open them all at once.
• IE View allows you to open a page or link in IE - dead handy for testing. And like it or not, you have to test with IE.
• Tabbrowser Extensions allows you to drag and drop tags, close loads of tags at once, and quite a few more things. Give it a try.
• Google Bar - a clone of Google's IE toolbar.

That's what I use, but your needs are probably different, so check out all the Firefox Extensions and see what you fancy.
