Help for Text Highlighter - Dynamic

Hi all,

I can't run the script Text Highlighter - Dynamic.

For example to search for "Highlighter" on a page I just modify the part

setUserPref( 'keywords', 'word 1,word 2,word 3', 'Set Keywords', 'Set keywords separated by comma\t\t\t\t\t\t\t\r\n\r\nExample:\r\nword 1,word 2,word 3', ',' );

No?

Thanks in advance.
