This is pointless, as the vast majority of browsers will assume domain prefixes and suffixes already (except for IE, probably, which is always 5 years or so behind feature-wise). Keyboards are getting big enough with all the web shortcuts and such...

With Mozilla variants, you have to download a plugin to do this, but Opera "out of the box" will go to www.amazon.com if you just type in "amazon", for example. If there's no .com by that name, it will try .net, then .org, etc. in whatever order you specify.

I dissagree with this idea, mainly on the princaple of lazyness.

Also, try this out in your Internet Explorer: Type in yahoo in the URL, and press Ctrl-Enter. It'll do the www. and the .com for you. Thus, they already have the lazyness built in.

Some browsers fill in those atomatically.

Could also be done with software macros.
