User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

Photos on IMDB do not load properly. To reproduce, go to an actor or actress page- Photo section. The photo loads for a split second and closes. The last good Nightly version was 08/06/2021,
Build ID 20210806213901 Linux x64 xfce, Manjaro, Unstable branch.
It works fine in FF Stable 90.0.2

Actual results:

The photo loads for a split second and closes.

Expected results:

The photo can be viewed and subsequent photos can be viewed as well.

Confirmed on Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0
Build ID: 20210808090543

Steps to reproduce

  1. Load https://www.imdb.com/name/nm0185819/mediaviewer/rm2349511169/

Actual result

The whole page loads for a split second then turns into a blank white page, even when Nightly is using night theme.

Expected result

The photo page can be viewed.

Notes

The page can be viewed if:

  1. layout.css.computed-style.throw-on-invalid-pseudo is false; or
  2. I disable javascript from d1zcggttmijv1z.cloudfront.net using uMatrix or from Nightly's devtool.
