Enable tracking query parameters stripping
URL query parameters (aka URL search parameters) are a major vector for cross-site tracking. They comprise what is perhaps the most significant category of cross-site tracking vector that remains unblocked in Tor Browser.
Fortunately, Firefox has announced that they will be enabling tracking query parameter stripping for Strict mode and Private mode. (As of Firefox 103, this protection seems to be enabled in Strict Mode only in Release.) It would be great if Firefox's feature can be enabled in Tor Browser and expanded to cover more parameters that Firefox doesn't, including Google's gclid and dclid and Microsoft's msclkid.
