What is the easiest way to make your browser refresh a page every say, 5 seconds?

Or for Firefox, use the following one-liner as a Greasemonkey script:

setTimeout(function(){ window.location.href = window.location.href; }, 5000);

Yes, Opera supports this feature out of the box. Go to the webpage, right click and select Reload Every.

See the following screenshot for illustration:
