Selection Highlighter is a Chrome add-on designed to enhance text visibility by automatically highlighting all occurrences of the user's current selection on the webpage. This tool is particularly useful for users who frequently need to reference specific text, making it easier to locate important information without manual effort. The extension is compatible with shadow DOM pages, ensuring broad applicability across different web structures.

In addition to its core functionality, Selection Highlighter offers customizable options, allowing users to toggle the highlighting feature on or off. Users can also modify default settings, such as highlight colors, to suit their preferences. The latest version includes enhancements like a configurable threshold to ignore certain selections and ensures that style tags are not highlighted, maintaining the integrity of the page's design.
