Hi,

I've managed to reproduce this issue using Firefox 63.0(20181018182531), Firefox Beta 64.0b3(20181022150107) and
Firefox Nightly 65.0a1(20181023222913)


Thank you for reporting!

Just to update, this is not specific to Windows 10. I happens on all Desktop systems.
Also, as we start using the blocking protection more and more, would it make more sense to create a web page where all the non working sites can be posted? Creating one bug report per website will become unmanageable very soon.

Cheers

So below are the domains to test:
- s.skimresources.com
- plugin.mediavoice.com
- sb.scorecardresearch.com
- cdn.taboola.com
- www.google-analytics.com
- ib.adnxs.com
- sync.search.spotxchange.com
- ads.pubmatic.com
- z.moatads.com
- plugin.mediavoice.com
- apx.moatads.com
- platform.twitter.com
- aka-cdn.adtech.de
- s-jsonp.moatads.com
- dis.criteo.com
- p.rfihub.com
- pixel.quantserve.com
- sync.mathtag.com
- aol-match.dotomi.com
- sync-tm.everesttech.net
- bh.contextweb.com

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

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- aolcdn.com (including all related domains)
- blogsmithmedia.com (including all related domains) 
and the slideshow is triggered but no images displayed.

I then Whitelisted:
- blogcdn.com (including all related domains)
- twitter.com (including all related domains)
and the images were displayed and slideshow could be closed. 

The other resources didn't help. 

So in conclusion:
- aolcdn.com is in Content category = [tp-content]
- blogsmithmedia.com and blogcdn.com are not listed
- twitter.com is in Disconnect list at Social = [tp-social]

Added uMatrix results.

Comment 6

[Thomas Wisniewski [:twisniewski]]

The image-galleries start working when I whitelist https://platform.twitter.com/widgets.js. It turns out that their scripts expect to be able to call window.twttr.widgets.load, or they break. Shimming like in bug 1519448 comment 3 seems to un-break it just fine.

Comment 7

[maroonmoon]

In Firefox 75.0, clicking the image doesn't even open the gallery view anymore. It just brings me to the top of the page.

The issue is not reproducible with ETP - Standard, but still occurs with ETP - Strict.

Tested with:
Browser / Version: Firefox Nightly 86.0a1 (2021-01-21)
Operating System: Windows 10 Pro

Changing the title so it reflects the above.
