Is WebP and AVIF Highlighter safe?

Low risk

WebP and AVIF Highlighter refetches page image URLs with extension permissions to classify their codecs.

When enabled, the extension runs on every webpage and sends image, srcset, and CSS background-image URLs from the page to its background service worker. The background worker fetches those URLs with WebP and AVIF Accept headers, then returns the detected codec and quality so matching page elements can be labeled.
