Hi Subham,

Would you be able to share a sample extension where not all of the rules are working?

There are many reasons why this can happen (for example, missing host permissions) and without seeing the extension it's hard to be sure what is happening. It is always possible there's a bug, but we do have lots of other extensions using the API and I haven't heard of anything similar in 129 yet :)

Thanks,

Subject: Inconsistent Enforcement of Declarative Net Request Rules - Test Extension Available

Dear Oliver Duck and the Chromium team,

I hope this email finds you well. Thank you for your responsiveness regarding the Declarative Net Request (DNR) rules issue. I've prepared a demonstration extension to illustrate that not all DNR rules are being enforced consistently.

Key Points:

1. Test Extension: https://github.com/subham8907/test
2. Installation: To reproduce the problem, please install the attached extension in a Chromium-based browser.
3. Testing Process: a. After installation, you can use your own prepared URL links to test the enforcement of rules. b. I've also included some sample URLs for testing in the extension.
4. Issue Description: You'll notice that not all DNR rules are being enforced as expected.
5. Reproduction Steps: a. Install the test extension b. Use the provided test URLs that should trigger all DNR rules c. Observe that some rules are not enforced as expected
6. Test URLs: Below are example URLs for each rule specified in the extension. These URLs contain tracking parameters that should be removed according to the DNR rules:
   1. MSN: https://www.msn.com/en-us/news/technology/article?cvid=123&ocid=456
   2. Amazon: https://www.amazon.com/product?pd_rd=123&pf_rd=456&qid=789&sr=0-1&keywords=example&linkCode=ll1&tag=sample-20&linkId=1234567890abcdef&language=en_US&ref_=as_li_ss_tl
   3. Google: https://www.google.com/search?q=example&ei=123&ved=456&uact=5&oq=example&gs_lcp=789&sourceid=chrome&ie=UTF-8
   4. X (Twitter): https://x.com/username/status/123456?s=20&t=abcdef&ref_src=twsrc
   5. Twitter (legacy): https://twitter.com/username/status/123456?s=20&t=abcdef&ref_src=twsrc
   6. Netflix: https://www.netflix.com/browse?trackId=123456&tctx=789
   7. TechCrunch: https://techcrunch.com/2023/10/08/article-title/?ncid=123&sr=456&sr_share=twitter
   8. Bing: https://www.bing.com/search?q=example&form=QBLH&sp=-1&sc=10-0&qs=n&sk=&cvid=123456789
   9. DuckDuckGo: https://duckduckgo.com/?q=example&t=h_&ia=web
   10. Facebook: https://www.facebook.com/story.php?story_fbid=123&id=456&mibextid=Nif5oz&hc_location=ufi
   11. General (with UTM and various tracking parameters): https://example.com/page?utm_source=newsletter&utm_medium=email&utm_campaign=spring2023&fbclid=123&gclid=abc&_ga=1.123456789.987654321&_gl=1*abcdef*_ga*

These URLs should have their respective tracking parameters removed when the DNR rules are properly enforced. Please test each URL to verify the behavior of the corresponding rule.

I would greatly appreciate if you could investigate this issue and provide any insights or potential solutions.

Thank you for your time and attention to this matter. I'm looking forward to your response and am available to provide any additional information or clarification you might need.

Hello chromium team and google please look into it

[Oliver Dunk]

Hi Subham,

Apologies for the delay here. I really appreciate you taking the time to share that code.

It does actually seem like some of the `urlFilter` conditions aren't matching when I'd expect them to. I haven't figured out more than that yet, but it does seem likely that there's a bug here.

If you have a moment, I'd encourage you to consider filing something at https://crbug.com.

I'll definitely be taking a look as well though and I'll keep you posted.

Thanks,

Oliver Dunk | DevRel, Chrome Extensions | https://developer.chrome.com/ | London, GB
