Just double click to highlight the places that word occurs. There are places that it won't work or may break the page. Things like Twitter that load content are unlikely to work at all. Some sites just have badly written javascript that breaks and prevents me from running my code. TODO: build a way to disable the extension on sites that you select (maybe because you don't want or because you found it won't work); Update: bugfix v1.0.1 - won't search when highlighting words in a textbox. updates v1.0.2 - add link to search google since the word is no longer highlighted.
