Highlighter only one word per Para Rated 3 out of 5 stars

The highlighter only highlights one word of search string in paragraph, and when u click multiple times on highlight ON/OFF, it highlight same words subsequently in the paragraph, Well this feature is very well working in previous edition of mozilla (in previous versions 4.0 or less), so i thought to bound to use previous non secure slow versions of mozilla, pls fix it..... i think it should work on both latest versions and for chrome
Pls make superfast highlighter version even option to disable other possible features to make its processing fast and user compatability....

Very very thankx in advance.......
