Works well with one exception Rated 5 out of 5 stars
The only thing lacking the breaking up bracketed searches; EG (apples|oranges). Google will search for a page with either 'apples' and/or 'oranges'. Google Toolbar used to divide these up into two find-on-page buttons.
Other than that, this is great. You can even use it to find words on a page without having to search with the engine for them. Just type the word in the search-bar and left-click outside of it and a button is generated.
Plus, you can search backwards by shift-clicking a word button, which Google Toolbar couldn't even do.
