Highlight Occurrences of the Selected Text is a free Chrome extension that allows users to quickly highlight all instances of a selected word or phrase on a webpage. By simply double-clicking a word or selecting a text fragment, users can see every occurrence highlighted, mimicking the functionality found in code editors. This feature enhances readability and makes it easier to track important information across web pages.

The extension automatically detects and highlights text even as the webpage changes, such as during infinite scrolling. It requires no configuration, as users can activate it with a single click on its icon. To ensure user privacy, the extension disables itself after navigation, requiring reactivation for continued use. Being open source, it offers transparency and security for users concerned about data safety.
