I know I’ve banged on about Firefox before, but it really is good. Go on, try it. It’s only a 4.5Mb download – pretty manageable even on a 56k modem – and it could really improve your browsing experience. It’s faster than Internet Explorer, and it saves you from all those unpleasant pop-ups and pop-unders and such like. If you really don’t like it, it only takes a minute to uninstall it again, but I don’t think you’ll want to do that.
They’re running a campaign at the moment, and they wanted to get to 1,000,000 downloads in ten days. They’ve just done it in four.
