Until Mozilla Firebird was released, I'd always used Internet Explorer. And why not? It came pre-installed, and it did what I wanted. I occasionally looked at the alternative - Netscape - but its excess baggage (mail client, newsreader etc) annoyed me, in the same way that "do you want fries with that?" does.
I was hooked - it had everything I'd wanted from a browser -- tabs, so I could surf without filling my task bar with windows; automatic pop-up stopping and banner-ad blocking. Cookie and password management. And best of all, a search bar that not only worked, but was customisable with plugins. Adios, IE!
And there's more ...
So, if you're running Mozilla, and fancy h2g2 in your search bar, feel free to install the h2g2 Mozilla Mycroft Plugin. It sits politely with all the other Mozilla search plugins, allowing you to quickly search your favourite information repositories.
