Pale Moon forum

In this site: http://www.autoportal.iol.pt/ i have problems to watch some videos, but not all the videos in the site, some play fine. In some articles where the video should appear is just an empty space, like in this one: http://www.autoportal.iol.pt/desporto/h ... m-da-nisto
I also have the browser Firefox 56.0.2 and the same thing happens, but with the Opera 51 browser there is no problem at all, every videos play fine.
I tried to watch the video with all the add-ons disabled and the problem remains.
Please can you help me about this problem?

Operating System: Windows 7 64 bit
Browser Version: 27.7.2

From my understanding opera 51 is based on chromium 64 so im assuming opera is using the same video codecs as chromium which perhaps pale moon does not support.Just a guess.

IE11 shows following warning when opening the page when i click on the video part:


This content can not be displayed in a frame
To protect the information you enter on this site, the publisher of that content has prohibited the content from being displayed in a frame.

Possible procedure: Open this content in a new window

Clicking on the warning opens the video.

Most likely that site is created in a sloppy way only Chrome can understand
