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?

After fixing some stupid string handling...

Tokeniser + Parser: 168ms-170ms (5.9-6.0MB/s)
Tokeniser + Parser, text only: 24ms (41.4MB/s)

More than two orders of magnitude difference between strcatting and using stored lengths. The size increase of storing a length is tiny and the benefit is huge. The lesson here is: for performance, never use strcat(), always store lengths, and only strlen() once.
