YT Clean Links is a lightweight, privacy‑first extension that automatically strips tracking parameters from YouTube links before they can be used to follow you across the web. It targets the newer si share identifier, playlist and radio parameters like list and start_radio, as well as common marketing and ad tags such as pp, utm_*, and gclid on both youtube.com and youtu.be URLs. This helps prevent YouTube from correlating who shared a link, where it was posted, and how it spread, while keeping the video itself and useful options (like timestamps) working normally. youtube The extension works on two levels. At the network level, it uses Firefox’s declarativeNetRequest API to rewrite navigation requests so tracking parameters are removed before the page even loads, without giving the extension access to the full stream of requests. On the page itself, a small content script cleans YouTube URLs in the address bar, intercepts the Share dialog’s clipboard writes, and sanitizes links and window.open calls, so any copied or clicked YouTube URL is automatically “cleaned” without user interaction. All processing happens locally in your browser; the extension does not collect, store, or transmit any personal data, does not log browsing history, and does not communicate with any external server, aligning with Mozilla’s emphasis on clear, minimal data practices for add‑ons. blog.mozilla
