The issue is related to `Tracking Protection` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “https://widgets.outbrain.com/outbrain.js” was blocked because content blocking is enabled.
The resource at “https://www.googletagservices.com/tag/js/gpt.js” was blocked because content blocking is enabled.
The resource at “https://www.googletagmanager.com/gtag/js?id=UA-125433852-1” was blocked because content blocking is enabled.
The resource at “https://widgets.outbrain.com/outbrain.js” was blocked because content blocking is enabled.
The resource at “https://static.addtoany.com/menu/page.js” was blocked because content blocking is enabled.

So below are the domains to test:
- ​widgets.outbrain.com
- ​www.googletagservices.com
- ​www.googletagmanager.com
- ​widgets.outbrain.com
- ​static.addtoany.com

I opened the URL in a fresh browser profile (Firefox Nightly 66, uMatrix installed, normal mode) and loaded the page. The social media icons are broken.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- addtoany.com (including all related domains)
and social media icons are correctly displayed.

The other resources didn't help. 

So in conclusion:
- addtoany.com is in Social category = [tp-social]

The icons show up and seem to work fine for me even in strict mode now, so this seems fixed.
