How about...? Rated 3 out of 5 stars

I don't think this meets my needs, but it does look good... although I can't try it because its not compatible with Firefox 3.6.10

What I would really like to find is a search function within Firefox that will allow me to:

1. Open a search box and enter an infinite number of word to search on a web page or web document
2. This search box will have Highlight and Colour Code options for all the different words I am searching... Also with an option to group words by highlight or colour code
3. Save and back up multiple search settings to continue search another time

Has anyone or can anyone design something like this?
