Add-on summary

Please note that this Add-on will only work on websites that use the Accept header to detect WEBP compatibility. It will not work on websites that always serve this format or that use other means, such as User Agent, to detect compatibility.

This add-on doesn't execute any JavaScript because it uses the declarativeNetRequest API from manifest v3. Check the source code for more information.
