Firefox Find Function

[gumboot]

I use quite a lot of the "find" function in Firefox 3.5.2 for researching technical publications on the internet. I don't like the fact that each time I search for a word using the "find" function under "tools", Firefox highlights the word on the very last line of the article ie the highlighted word is at the very bottom of the page.

I would prefer it if Firefox could display the highlighted word around the centre of the page so that I can read the whole sentence in better context rather than have to scroll down when it appears on the last line displayed.

I've searched for an add-on for Firefox to solve this problem but I've not been able to find one.

Is there a Firefox add-on that will display a highlighted word in the centre of the page rather than on the bottom line? If not, is there a registry tweak that will do the same?

Thanks all.
