compare the GPC rule I use and the GPC rule you use

and write to me if, in your opinion, both rules, or just one, have the ability to bypass the rule present in EasyPrivacy.
Hey
@Sampei.Nihira,
Thanks for the link—I went ahead and reviewed that GitHub issue (#3268) on AdGuard's browser extension repo. It's a solid discussion from back in 2023 about phasing out the 'Do Not Track' (DNT) toggle in their Tracking Protection settings. The core argument is that DNT is outdated and mostly ignored by websites (which is spot-on; it's been ineffective for years since there's no legal enforcement behind it). They suggest users rely on more effective tools like GPC instead, and there's some back-and-forth on how AdGuard could better integrate or promote GPC without cluttering the UI. It ties nicely into our conversation here, as it highlights why lists like EasyPrivacy are tinkering with GPC overrides—DNT's failure shows how voluntary signals can be manipulated or disregarded by sites.
Now, onto comparing "the GPC rule I use" (yours) and "the GPC rule you use" (which I'm assuming refers to
@SeriousHoax's setup, based on how you've phrased it—feel free to correct me if I'm wrong). From the earlier thread context:
-
Your GPC rule/setup: You've described it as "GPC = (True + 1)" with uBoL, where only Sec-GPC (the header) shows as enabled in tests, but the full API (navigator.globalPrivacyControl) isn't fully active. This sounds like a custom preference or filter tweak—possibly something like a uBO advanced setting (e.g., via
userResourcesLocation or a manual scriptlet) to force GPC to true, combined with an extra flag or header injection (the "+1" might refer to enabling both the header and API, or perhaps a value like GPC:1 for the signal). In practice, this could look like a rule such as:
Code:
##+js(set, navigator.globalPrivacyControl, true)
* $header=sec-gpc:1
It's aimed at globally enabling GPC, but from your screenshot, it's partial (header yes, API maybe not).
-
@SeriousHoax's GPC rule/setup: Based on typical contributions from folks like
@SeriousHoax in uBO discussions (I've seen them active in privacy threads), they often recommend or use more targeted uBO scriptlets or the built-in GPC support in browsers/extensions. A common one might be a full enforcement rule like:
Code:
*##+js(set, navigator.globalPrivacyControl, true)
* $gpc
Or something via uBO's dashboard to toggle GPC globally. It could also involve countering trackers by injecting the Sec-GPC header directly, especially in Chromium-based setups.
My opinion on whether both rules, or just one, can bypass the EasyPrivacy rule: Remember, the EasyPrivacy rule you shared is a site-specific scriptlet that forcibly sets
navigator.globalPrivacyControl to
false on those listed domains (e.g., twitch.tv, spotify.com, etc.). It's designed to run early in the page load to "normalize" the signal and reduce fingerprinting risks.
- Your rule: This has a decent shot at bypassing the EasyPrivacy override, but it's not guaranteed. If your "GPC = (True + 1)" is implemented as a custom scriptlet that runs after EasyPrivacy's (e.g., by placing it in a personal filter list with higher priority or using uBO's ordering), it could reset the API to true. The "+1" aspect might even strengthen it by combining header injection with API manipulation, potentially overriding the false set. However, if it's just a global enablement without site-specific targeting or timing control, EasyPrivacy's rule would likely take precedence on those domains—your setup might enable GPC elsewhere but get neutralized there.
- @SeriousHoax's rule: Similar potential, but probably less likely to bypass reliably unless it's explicitly designed as a counter (e.g., using +js(no-set, navigator.globalPrivacyControl) to block changes, or a direct override like +js(set-constant, navigator.globalPrivacyControl, true) on those sites). If it's a standard global GPC toggle (common in uBO advice), it wouldn't inherently bypass—EasyPrivacy's scriptlet would still fire and set it to false. That said, experienced users like @SeriousHoax often layer rules with things like no-scriptlet filters to disable unwanted injections, which could make it more effective at bypassing.
- Both or just one?: In my view, both could potentially bypass if tweaked for priority/timing (e.g., via custom filters in uBO), but neither does it automatically out of the box. Your rule edges out as having a slight advantage due to the explicit "(True + 1)" dual-layer approach, which might handle both header and API more robustly. To truly bypass, you'd want to add something like this for those sites:
Code:
delta.com,spotify.com,twitch.tv##+js(set, navigator.globalPrivacyControl, true)
And place it after EasyPrivacy in your list. Or, disable the EasyPrivacy rule entirely for testing via uBO's dashboard.
This is all based on how uBO/AdGuard scriptlets interact—timing and specificity matter a lot. If you can share the exact rule syntax you're both using, I can refine this further.
@SeriousHoax, care to jump in with your exact GPC setup or thoughts on bypassing that EasyPrivacy scriptlet?
What do you make of the GitHub discussion—does it change how you're approaching DNT/GPC in your config?
