This is a brilliant little extension that lets you search the web using an image instead of words as the search term. This is handy if you are looking for the original version of an image, or even a modified version thereof. You can right-click on an image on a webpage and then search Google for similar images.
When you are on the web a lot, you are sure to come across something you want to search for more information about, and Highlight to Search makes this easier. Simply highlight the words you’d like to search for, and click the magnifying glass for a new tab with a search in it.
