Why browsers are bloated

Let's reinvent the fucking scrollbar, which every goddamn platform with a UI already has, and make it behave subtly different from the native one!

Right-click a native scrollbar in some other app:
- Scroll Here
- Top
- Bottom
- Page Up
- Page Down
- Scroll Up
- Scroll Down

Right-click a scrollbar in Chrome:
- Back
- Forward
- Reload
- Save As...
...

Right-click a scrollbar in Firefox and Opera:
Absolutely fucking nothing happens!

What the fuck!? How did these terminally retarded idiots get involved in creating one of the most important pieces of software to the average user?

What will be the "killer feature(s)" of The Next Browser? Being smaller and faster, completely pubic-domain and open-source, and easy-to-use but also powerful UI is what I'm thinking of.

The next browser? mate by the looks of it you can just start thinking about the next protocol. Not even the nuttiest nut is going to be able to go without a client that renders his bank apps and does Flash. If we're to get in there it has to be from the side.

We need something in between IRC (decentralized, data oriented, native UI, "instant") and the Web (application oriented). With a strong focus on privacy and security. We can build this platform on top of HTTP for all I care but HTML5 has gots to go.
