The issue is related to `Video` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “https://vt.adition.com/d?lid=6615852135394246806&n=1810&c=2782765&b=9018046&cu=3354963&vt=0&elapsed=2621&ma=0&suvt=0&h=8&v=338&vt_50=0&vt_60=0&vt_100=0&vt_cust=0&version=6” was blocked because content blocking is enabled.
The resource at “https://dc542.s407.meetrics.net/bb-mx/submit?/okoPM5y/JLklFCTkzF8PBojAAAAAAHAAAAPkLArHA9OAGAAAAP4JIMCArGAGAAAAPOICAAAAAAIAAAARksFA” was blocked because content blocking is enabled.
The resource at “https://www.google-analytics.com/analytics.js” was blocked because content blocking is enabled.
The resource at “https://imagesrv.adition.com/js/srp.js” was blocked because content blocking is enabled.

So below are the domains to test:
- ​vt.adition.com
- ​dc542.s407.meetrics.net
- ​www.google-analytics.com
- ​imagesrv.adition.com

I opened the URL in a fresh browser profile (Firefox Nightly 65, uMatrix installed, normal mode) and loaded the page. The parts background videos is not displayed.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- ad-balancer.at (including all related domains)
- adition.com (including all related domains)
- jquery.com (including all related domains)
and the video is loaded.

The other resources didn't help. 

So in conclusion:
- adition.com is in Advertising category = [tp-ads]
- ad-balancer.at and jquery.com is not listed

Worksforme. The page layout has changed, and I no longer see any videos or obvious breakage, even in strict mode.
