Adguardfilters: EasyPrivacy blocking multiple sites links from opt-in emails on gmail [iOS]

[yourduskquibbles]

Description:

• Current behaviour:

When EasyPrivacy is enabled, clicking on some links in gmail that include tracking paramaters such as an amazon order info, a fedex tracking link, a news story from seekingalpha.com, or an article from quora.com, in gmail app on iOS gets blocked by 1 or more filters in EasyPrivacy list.

My best guess is that this is false positive caused by some portion of the link in the email including track in the URL [See URL formats below] but I'm unable to fully debug iOS Safari issues because no MacOS to test with.

Example links getting blocked by EasyPrivacy when clicked via gmail tracking card/link that I tested as BLOCKED by EasyPrivacy are below:

• Amazon.com - link format: https://www.google.com/url?q=https://www.amazon.com/gp/r.html?C%3D[redacted]%26K%3D[redacted]%26M%3Durn:rtn:msg:[redacted]%26R%3D[redacted]%26T%3DC%26U%3Dhttps%253A%252F%252Fwww.amazon.com%252Fgp%252Fyour-account%252Fship-track%253Fie%253DUTF8%2526orderId%25[redacted]%2526packageIndex%253D0%2526shipmentId%25[redacted]%2526ref_%25[redacted]_scr_pt_track%26H%3D[redacted]%26ref_%3D[redacted]_scr_pt_track&source=gmail&ust=[redacted]&usg=[redacted]

• Expected behaviour:

links clicked through gmail app should load properly even if they have some tracking metrics included in the link from the provider.

It is not Easylist issue. iOS ralated only.

It is not Easylist issue. iOS ralated only.

No exception filter is possible to counteract this behavior? Only option is disable EasyPrivacy?

Sorry if these are noob questions, I'm not very familiar with the limitations of iOS Safari content blocker vs desktop full featured adblocker.

Please check these rules:

@@.com/tracking?
@@/track?*&ref=
@@/track_click?
@@||amazon.*/gp/r.html?

[Alex-302]

They are for test only. I will make specific exclusions for content-blockeds only.

[yourduskquibbles]

@@.com/tracking?
@@/track?*&ref=
@@/track_click?
@@||amazon.*/gp/r.html?

Tested with EasyPrivacy enabled and CONFIRMED these user filters all work - content from the 4 example sites loads correctly now.

[Alex-302]

Ok, please check these rules instead of previous

@@||fedex.com/tracking?
@@||amazon.*/gp/r.html?
@@/track?*&ref=$~script,~xmlhttprequest,~other
@@/track_click?$~script,~xmlhttprequest,~other

Please wait a minute after changing filters, do not close AG window.

FedEx still blocked - may be case sensitive - @@||fedex.com/Tracking? instead of @@||fedex.com/tracking? Will test that change and report back.

Other 3 work great though 👍

just tested, neither @@||fedex.com/Tracking? or @@||fedex.com/tracking? work, still blocked

[Alex-302]

Correct rule: @@://www.fedex.com/Tracking?

[yourduskquibbles]

@@://www.fedex.com/Tracking?

This works! 👍👍
