About your download

Allow CORS: Access-Control-Allow-Origin is a Firefox add-on designed for web developers to facilitate cross-domain Ajax requests in their applications. By enabling this add-on, users can bypass the default restrictions imposed by modern browsers on Cross-Origin Resource Sharing (CORS), which is essential for accessing resources from different domains. The add-on operates in a straightforward manner, requiring minimal setup to enhance the functionality of web applications.

Once installed, the add-on remains inactive until the user activates it by clicking on the toolbar icon, which changes color to indicate its status. This intuitive design ensures that developers have control over when to enable cross-domain requests. Additionally, the add-on provides a feature for reporting bugs, ensuring that users can contribute to its improvement.
