Whitelisting both cdn.adswizz.com and synchrobox.adswizz.com seems to work. Perhaps we could find a way to shim https://cdn.adswizz.com/adswizz/js/SynchroClient2.js* and/or https://synchrobox.adswizz.com/register2.php*.

Just shimming both of the URLs in comment 1 with an empty script is enough to work around the issue on this page.

The issue doesn’t reproduce on 8/23 Nightly 93.0a1 build, nor in Beta 92.0.0-beta.6, with Lenovo Tab M10 (Android 10).

[Simona Badau, Desktop QA]

I can't reproduce this issue on the latest Nightly 93.0a1 nor on the latest Firefox 92 beta 7 on Windows 10 x64 - I could not reproduce the initial issue either - tried with ETP set to strict, in private browsing and with Smartblock disabled (extensions.webcompat.enable_shims set to false).

I can confirm that the issue is no longer reproducible.

Tested with:

Browser / Version Firefox Nightly 93.0a1 (2021-08-23) (64-bit)
Operating System: Windows 10 PRO x64
