Hi,

How can I force Nightly to play a media type ? Per instance, the top main video here : https://www.lapresse.ca/international/asie-et-oceanie/2025-12-23/coree-du-nord/kim-jong-un-inaugure-un-complexe-hotelier-dans-une-station-de-montagne.php

Best regards iBenny

The site is not broken since the video plays in 2 other browsers (Brave and Vivaldi).

The message displayed on top of the video is : 'The media could not be loaded, either because the server or network failed or because the format is not supported.'. I lean towards the latter cause : "format not supported" so... how to configure Nightly to accept the format ? I think it is a 'mpeg' video !

Hi

Thank you for helping test future updates to Firefox at the Nightly stage, we really appreciate it.

Does the video play for you in a Release copy of Firefox?

What do you mean ? If I have a standard FF installed ? I do have Palemoon and the video area is blanked with a video play bar at the bottom that don't work !

Please, check, your, Enhanced Tracking Protection in Firefox.

Under, Nightly, i tested, What to do if a site seems broken, it works.

Sorry Paul, I skipped too fast the solution before your post. Thanks for passing by !

I tweaked the Privacy and security | Enhanced Tracking Protection | Custom and unchecked the second setting and the issue was resolved.
