Looking for a Firefox extension?

Is there an extension for the Firefox "find" (ctrl+F) that lets you have certain searches saved?

An example. I am playing a video game and I'm using a walk though posted online and I read what I need to do and I go play the game, what I'm looking for is something that would let me save the games level name into the "find" and so the next time I need to get some help I'd just have to go to the site and pick from a set of words (in this case it's the levels name) in the "find" and find the section I'm looking for.

Thanks for the help.
