Is Twitter & X Video Downloader safe?

High risk

Twitter & X Video Downloader sends site cookies from matched social-media pages to api.x-downloader.com.

When the content script loads on X/Twitter, Instagram, YouTube, TikTok, or x-downloader.com pages, it triggers a tracking request. The background script reads cookies for the current hostname, combines them with browser language, user agent, hostname, and a persistent user id, then sends the encoded data to the vendor endpoint.
