Images can’t be downloaded in Firefox Nightly using beta version

I get the following error in the console log:

Uncaught (in promise) 
error { target: img, isTrusted: true, srcElement: img, eventPhase: 0, bubbles: false, cancelable: false, returnValue: true, defaultPrevented: false, composed: false, timeStamp: 75557, … }

The stable version of the site works fine.

I get the same error on Chrome v97 & iOS Safari (iOS 15.2).

I'm completely unable to download images.

Edit: looks like I only receive the error for certain images. e.g the "popular images" tab -> HMRC
