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?

Unfortunately, most programming languages do not support multiple dispatch.

Argument type Return type
C++ (since 1998), Java (since J2SE 5.0), Scala, D Invariant Covariant
C# Invariant Invariant
Sather Contravariant Covariant
Eiffel Covariant Covariant

Not one of the mainstream languages gets it right. Only Sather which I haven't even heard about prior to readint this article. All corporate languages are shit.
