There is a JS exception that is raised from this code from https://ekstat.com/js/ek$i-defer.js?v=vC1VbMn-3Qn5jk18aEwSjykWrddENxjK6NNNywAgiWM1:

typeof r[0].children[0].children[0].children[0] == 'undefined' && typeof e == 'undefined' && t.open(f, '_self')

r[0].children[0].children is an empty array here, presumably due to some elements missing from the DOM due to blocking.

This can be reproduced on desktop in strict mode and/or in a private window.

The links work if I allow these scripts to load:

https://www.googletagservices.com/tag/js/gpt.js
https://securepubads.g.doubleclick.net/gpt/pubads_impl_2020040702.js

The page is relying on the ads being loaded and shown, or at least for the ad scripts to inject some nodes. This is done when they make calls like this in their scripts:

top.googletag.display('div-gpt-ad-1586289900942-0');

And when I shim the googletag object completely enough so that it can accept their site's commands (mainly as no-ops aside from the display method actually adding the nodes they expect -- a single div will do), then I can click the links as expected. So we can likely handle these kinds of cases by shimming gpt.js (it appears that the second pubads_impl script can remain blocked with my minimal shim).

I can't reproduce the issue on my side, with ETP - Standard or Strict, I can single tap/click the links and be redirected accordingly.

Tested with:
Browser / Version: Firefox Nightly 210201 (🦎 87.0a1-20210129095945), Firefox Nightly 87.0a1 (2021-02-01)
Operating System: Samsung Galaxy S8 (Android 9) - 1440 x 2960 pixels, 18.5:9 ratio (~570 ppi density), Huawei P20 Lite (Android 8.0.0) - 1080 x 2280 pixels, 19:9 ratio (~432 ppi density), Windows 10 Pro

Karl does it still occur on your side?
