Confirmation Checklist

• I confirm that this feature is not already present on the latest release of Phoenix. You can check what the latest version is on the Releases page.
• I confirm that this feature has NOT already been suggested on the Codeberg issue tracker, the GitLab issue tracker, and/or the GitHub issue tracker.

Please explain your proposal with as many details as necessary (Ex. what you're suggesting, why you're suggesting it, what need you thinks it will fill, who it will benefit, etc...).

The privacy.query_stripping.strip_list misses a few well known tracking parameters that are seen regularly on the Internet. Sharing so that this gets added, if deemed essential.

_kx is used by Klaviyo, an email and SMS marketing automation platform.

gbraid is used by Google Ads as a privacy-preserving click identifier on iOS 14.5+ devices.

igshid is used by Instagram to track the source of traffic.

@fossil535 Thank you for the issue!

_kx

Unfortunately, this appears to cause breakage.

igshid

Added! (For reference, Brave's query stripping list does include this parameter, but only sets it for instagram.com. AFAICT it doesn't cause breakage when stripped from other sites though, so I see no reason not to set it. Going to go through their per-site list and see if there's any other entries we can get from there that don't cause breakage as well).

utm_campaign

It looks like this causes breakage with ex. Google Maps on Android (1, 2). Because this is the only instance of breakage I can find and it only seems to impact Android, I'll add it for Desktop - especially valuable IMO due to how widely used it is. (For reference, looks like Brave is setting this by default as well, but only for copying clean URLs for some reason. Will go through and add other missing rules where applicable/relevant from there too).

utm_medium
utm_source

Added both! (For reference, looks like these are also set by Brave in the file for copying clean URLs).
