Prevent tracking based on link decoration via query string or fragment

ITP 2.2 is reducing the lifetime of cookies set via document.cookie when the navigation came from a tracking-enabled page and the destination URL includes query string parameters or a fragment: https://webkit.org/blog/8828/intelligent-tracking-prevention-2-2/

We already block the third-party scripts that would be extracting these IDs and setting a first-party tracking cookie, but we could in theory go further by:

• emulating the cookie lifetime restriction, or
• stripping out tracking query string parameters (e.g. gclid, fbclid, msclkid and mc_eid).

Thanks for expanding on your use case. I’ve filed https://github.com/brave/brave-browser/issues/13242 to track this. The fact that it’s been requested more than once suggests that many more developers are likely to want this too.

is possible to find to msclkid in bing ads

You’ll still see a msclkid parameter in links because we don’t rewrite links inside of pages, but if you click on the link, the msclkid parameter will be removed before the connection to the other server.
