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?

This page, which has grown since the last time I benchmarked it (>>123), now takes just under 10ms.

memcpy() is superior.

>>135
If you can't do the absolutely trivial arithmetic needed for determining the right lengths ("maths is hard!") you should not be doing any programming at all.

For my use the best option is probably null-delimited with prefix-length, i.e.

char *to_nstr(char *str) {
long sl = strlen(str);
char *t = malloc(sizeof(long) + sl + 1);
if(t) {
*((long*)t) = sl;
memcpy(t+sizeof(long), str, sl + 1);
t += sizeof(long);
}
return t;
}

Read-only-compatible with existing C APIs, but contains a length that can be used by functions aware of it.
