[FYI] Bugzilla issue suggesting core Firefox Tracking Protection should protect from URL/queryparam-based tracking

[ronjouch]

Hi, ClearURLs users and contributors.

Just a "FYI" issue to publicize that I created Firefox Bug 1697982 - Firefox Tracking Protection should protect against URL/queryparam-based tracking (like addons ClearURLs/NeatURL do), which suggests the protection offered by addons like this one should be baked in Firefox.

• It was received positively by Mozilla folks, who acknowledge the rationale.
• No promises yet, but it's "on [their] radar & roadmap".
• Please complement with extra information that may help Mozilla understand / analyze / scope this better.
• Please refrain from noise-only "Me too" / "+1" comments. Use Bugzilla's Vote/Follow features if you don't have anything to add.

@ authors / maintainers: not expecting you keep this "bug" open, of course. Feel free to close now or anytime in the future. Thanks for your work 🙂.

And please do do that - I suspect it being built into FF is the most likely way this functionality is going to get into FF for Android.

I found that Firefox 102 introduced built-in removal of tracking query string parameters.
-> In Privacy & Security settings, ensure Enhanced Tracking Protection is set to Strict (required to activate the query string feature). The default set of removed query params is limited, but you can configure your own via the privacy.query_stripping.strip_list pref as a space-separated list.

I found this page documenting it (no idea if it's up-to-date)
https://firefox-source-docs.mozilla.org/toolkit/components/antitracking/anti-tracking/query-stripping/index.html

What is the ship state of this protection in Firefox?

Query stripping is enabled in release in ETP strict with an initial list of query params:

    mc_eid
    oly_anon_id
    oly_enc_id
    __s
    vero_id
    _hsenc
    mkt_tok
    fbclid

The list has grown a little since:
