Is Px Downloader safe?

Clean risk

Px Downloader modifies CORS headers on Pixiv's image CDN to enable cross-origin downloads from pixiv.net pages.

Px Downloader is a browser extension for downloading images and animations from the Pixiv art platform. It injects a content script on pixiv.net pages and intercepts network responses from pximg.net (Pixiv's image CDN), rewriting the Access-Control-Allow-Origin header to '*' to permit cross-origin requests. No user data is transmitted to external parties; all processing is local.
