Chrome/Eclipse-like Scrollbar Search Highlighter for Firefox

I would love for some simple HTML(5?) API where certain anchor elements automatically show up on the scroll bar. That way, for instance, you could have a huge document split into chapters visible from the scroll bar, or a blog post where you can just glance at the scroll bar to see how long the article is and how many comments there are.

Something like `<a rel="scroll">`

Search inside a webpage is broken on all browsers, as it tries to find an exact string match: it's impossible to find a "paragraph", for example, that contains two words that aren't next to one another.

(The problem is: what's a paragraph in a webpage? But maybe a paragraph is simply a block element that doesn't itself contain other block elements.)

Why not just ... use Chrome.

I'm less concerned about minor UI enhancements, and would much rather have a regex-capable search box.
