Browser extension

Small, focused software modules that directly enhance and customize the functionality of a web browser (Chrome, Firefox, Edge) using standard web technologies.

Browser extensions are compact software packages that inject new features or modify existing behavior directly into a host browser, such as Google Chrome, Mozilla Firefox, or Microsoft Edge. These tools, often built using standard web technologies (HTML, CSS, JavaScript), operate with specific permissions to execute tasks like content modification or data handling. Key examples include productivity boosters (e.g., Grammarly, Todoist), security layers (e.g., uBlock Origin for ad blocking), and utility managers (e.g., Bitwarden for password management), fundamentally customizing the user's web experience beyond the browser's default capabilities.
