Mark Your Search is a free Chrome extension developed by yancoolay under the Browsers category, specifically under Add-ons & Tools. This extension allows users to easily mark desired text on any webpage and search through popular search engines.

With Mark Your Search, users can simply left-click on any text to mark it, which triggers a cool tooltip displaying two options: a magnifying glass icon for search and a "copy" icon for copying the text. Clicking on the magnifying glass icon opens two new tabs with the marked text as the search query.

Please note that upon installation, users may encounter a popup requesting access to data on all websites. Mark Your Search offers a convenient way to search for text snippets quickly and efficiently on the web.
