There isn't much to say about this thing, other than its probably the most useful thing I have ever used in FireFox...

Check it out for yourself ;)

dunno, adblock beats it for me. :D but a very useful tool

<span style="color: lightblue">Nothing there that hasn't been possible before, with the only possible exception of the auto-linking street addresses (although, I imagine it would be trivial to do with a Greasemonkey script). The 'browse by name' would also be possible in Firefox; implement it in a GET based search engine, and then put the URL in the relevant pref - for someone with the resources to host a website, this wouldn't be hard; for someone with the resources to host Google, it would be trivial - they could even tie it into their existing homepage (as a minor change in behavior))
