The issue is related to `tpimages` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “https://static.criteo.net/js/ld/ld.js” was blocked because tracking protection is enabled.
The resource at “https://yandex.st/share/share.js” was blocked because tracking protection is enabled.
The resource at “https://www.googletagmanager.com/gtm.js?id=GTM-TBXRQ6” was blocked because tracking protection is enabled.
The resource at “https://static.criteo.net/js/ld/ld.js” was blocked because tracking protection is enabled.
The resource at “https://mc.yandex.ru/metrika/watch.js” was blocked because tracking protection is enabled.
The resource at “https://vk.com/share.php?act=count&index=0&url=https%3A%2F%2Fwww.tez-tour.com%2Fru%2Fvrn%2Fhotel.html%3Flang%3Dru%26city%3Dmsk%26id%3D373052” was blocked because tracking protection is enabled.
The resource at “https://graph.facebook.com/?id=https%3A%2F%2Fwww.tez-tour.com%2Fru%2Fvrn%2Fhotel.html%3Flang%3Dru%26city%3Dmsk%26id%3D373052&callback=jsonpCallbacks.cb797391385533054” was blocked because tracking protection is enabled.
The resource at “https://connect.mail.ru/share_count?callback=1&func=jsonpCallbacks.cb9052953277566049&url_list=https%3A%2F%2Fwww.tez-tour.com%2Fru%2Fvrn%2Fhotel.html%3Flang%3Dru%26city%3Dmsk%26id%3D373052” was blocked because tracking protection is enabled.

So below are the domains to test:
- static.criteo.net
- yandex.st
- www.googletagmanager.co
- static.criteo.net
- mc.yandex.ru
- vk.com
- graph.facebook.com
- connect.mail.ru

I opened the URL in a fresh browser profile (Firefox Nightly 63, uMatrix installed, normal mode) and loaded the page. The images are not displayed.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- yandex.st
and images were displayed.

The other resource didn't help. 

So in conclusion:
- yandex.st - is in Advertising category = [tp-ads]

The images are working for me in strict mode now on today's nightly build. Oana, do they also work for you now?

Comment 7

[Oana Arbuzov [:oanaarbuzov]]

Yes, I can confirm it works fine now - images are displayed both with Standard and Strict TP.
