Tool to highlight and annotate text on websites?

Question

When I read something I need to underscore what I like, or what I think is important, and to take notices about that read, near on that current paragraph.

So, does anyone know a Firefox add-on or something else (another browser, any other application) which can provide me such a functionality?

ps: I've tried some research tools as Zotero, but it is not what I'm looking for.

Answer 1

I find a better one: Diigo

Answer 2

Try Wired-Marker:

It is a permanent (indelible) highlighter that you use on Web pages. The highlighter, which comes in various colors and styles, is a kind of electronic bookmark that serves as a guide when you revisit a Web page. The highlighted content is automatically recorded in a scrapbook and saved.

Answer 3

There's quite a few sticky-note/highlighter add-ons. One of the nicer ones is Diigo. It has the option to integrate with the Diigo website so you can keep track of your important selections later on.

This extension also has the functionality you're after. It's more about saving pages than simply highlighting some text for mater on though.
