The issue is related to `trackingprotection` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “https://www.googletagmanager.com/gtm.js?id=GTM-5NH84B” was blocked because content blocking is enabled.
The resource at “https://static.addtoany.com/menu/page.js” was blocked because content blocking is enabled.
The resource at “https://static.getclicky.com/js” was blocked because content blocking is enabled.
The resource at “https://www.google-analytics.com/analytics.js” was blocked because content blocking is enabled.

So below are the domains to test:
- ​www.googletagmanager.com
- ​static.addtoany.com
- ​static.getclicky.com
- ​www.google-analytics.com

I opened the URL in a fresh browser profile (Firefox Nightly 65, uMatrix installed, normal mode) and loaded the page. The photo can't be viewed in full screen.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- addtoany.com (including all related domains)
and the photo is displayed in full screen.

The other resources didn't help. 

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

Added uMatrix results.

Weird. It works, but the first time I fullscreen the image, there is a scrollbar and it is vertically too short. But it does not seem related to tracking protection. This seems like a regular webcompat issue now.

In a new profile in Windows, I get expected behavior.

But, in Chrome Canary, I can reproduce what Tom saw (will upload photo).

Given that, I think we should close as INVALID (non-compat).
