These are resolved with a cookieless background request, so the affiliate attribution cookie is never written to your cookie jar, even
  though you still reach the correct destination.

<strong>How it works</strong>
  The extension hooks top-level navigations through webRequest.onBeforeRequest. Known tracking and affiliate parameters are stripped synchronously with no network cost. Shortener hosts are resolved in the background with credentials: "omit", which means no cookies are sent to or accepted from the shortener's redirect chain. Resolved URLs are cached so a given short link is never re-fetched.

<strong>What it does not do</strong>
  - Does not touch XHR, fetch, or analytics beacons — only user-visible navigations. API calls that legitimately depend on query parameters are left alone.
  - Does not send any data anywhere. No telemetry, no remote rule list, no analytics, no update pings beyond Firefox's standard version check.

<strong>Permissions</strong>
  - webRequest / webRequestBlocking — required to rewrite a URL before the request is sent. Without blocking webRequest, the tracker has already been contacted by the time a parameter can be removed.
  - Access your data for all websites — required because tracking parameters appear on every site, not on a fixed list. The extension only ever reads the URL of each top-level navigation; it does not read page contents.

<strong>Privacy</strong>
  This extension collects nothing. There is no remote server, no account, no analytics. The only outbound traffic it generates is the cookieless HEAD request used to resolve shorteners you click — and that request goes to the shortener's own host, not to any server
  operated by this add-on.
