STR: 1. Enable Tracking Protection 2. Load https://threatpost.com/mozilla-tests-dns-over-https-meets-some-privacy-pushback/130765/ 3. Search for the text "draft-04" in the page and click the "draft-04" link. EXPECTED RESULT: Firefox should load the linked page: https://datatracker.ietf.org/doc/draft-ietf-doh-dns-over-https/?include_text=1 ACTUAL RESULT: Nothing happens. Is the IETF page load blocked because the domain name "datatracker.ietf.org" contains the substring "tracker"? Firefox will load the IETF page if you paste the https://datatracker.ietf.org/doc/draft-ietf-doh-dns-over-https/?include_text=1 URL in the address bar directly. Also, I am able to load the IETF page when clicking a link from google.com, so I'm not what is unusual about threadpost.com's link. https://encrypted.google.com/search?hl=en&q=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft%2Dietf%2Ddoh%2Ddns%2Dover%2Dhttps%2F%3Finclude_text%3D1

No, the domain would have to be on the Disconnect list. We cannot match on partial hostnames in the URL Classifier, we need at least ETLD+1. It looks like all of the external links in the articles are broken: Morecowbell and QuantumDNS -> https://gnunet.org/sites/default/files/mcb-en.pdf Maybe they have some kind of link-tracking or redirection that breaks when we block Google-Analytics or something like that.

This page loads the following script: <https://assets.kasperskycontenthub.com/wp-content/plugins/bwp-minify/min/?f=wp-content/plugins/kaspersky-tracking/js/external-tracking.js,wp-includes/js/wp-embed.min.js,wp-content/plugins/gravityforms/js/placeholders.jquery.min.js,wp-content/plugins/akismet/_inc/form.js,wp-content/plugins/doubleclick-for-wp/js/vendor/jquery.dfp.js/jquery.dfp.min.js,wp-content/plugins/doubleclick-for-wp/js/jquery.dfw.js&ver=1526649031> This script bundles https://www.npmjs.com/package/jquery.dfp, which registers this event handler on the body element: https://gist.github.com/ehsan/64c8fd9ccb3dc4cf1831a594c326e8a6 This script tries to call the ga() function for all external links, but because we block Google Analytics(), that call fails and all external links break.

Tested the issue and is seems to be fixed with Tracking Protection Basic or Strict enabled on a clean profile. [Tested with:] Browser / Version: Firefox Nightly 63.0a1 (2018-08-09) Operating System: Windows 10 Pro @Chris Peterson can you still reproduce the issue?

(In reply to Oana Arbuzov [:oanaarbuzov] from comment #3) > @Chris Peterson can you still reproduce the issue? Nope. The draft-04 link currently loads as expected in Firefox 61 and 63 with both basic and strict Tracking Protection.
