Webextyökalujen

Webextyökalujen, often referred to as WebExtensions, is an API system that allows developers to create add-ons or extensions for web browsers. This system was largely developed by Mozilla for Firefox and has since been adopted by other browsers, including Google Chrome, Microsoft Edge, and Opera, with some variations. The primary goal of WebExtensions is to provide a standardized and secure way for developers to extend browser functionality.

Extensions built using the WebExtensions API can perform a wide range of tasks. These include modifying web page content, managing browser tabs and windows, interacting with network requests, storing data, and much more. They are designed to offer powerful capabilities while maintaining a strong focus on user privacy and security. This is achieved through a permission-based system, where extensions must explicitly request access to specific browser features or user data, and these permissions are clearly displayed to the user before installation.

The development of WebExtensions is typically done using web technologies like HTML, CSS, and JavaScript. This familiar skillset makes it accessible to a broad range of developers. The API is well-documented and provides a consistent interface across different browsers, which simplifies the process of creating cross-browser compatible extensions. While the core API is similar, minor differences in implementation or available APIs might exist between browsers, requiring some adjustments for full compatibility. Overall, WebExtensions represents a modern and robust framework for browser extension development.
