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?

I just don't know anymore... Shit going down on Syria, World's economy still stagnant, the kikes yet live, and in my retreat to my only place of confort I can't even find solace online. Firefox is going down hill, half of the websites I visit give me some Apache Mod error, other websites like Motherless reject my user agent, there are no decent browser alternatives. I just want to browse the web, I just want to be able to use links2 in Windows as well and not be tied down by retarded design majors and their inconsistent shit online.
