In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

Hi jasonz, what problem are you having with video in Firefox?

When decoding videos that were encoded using a patented codec, Firefox uses the Windows Media Foundation. Some versions of Windows are unbundled and in that case, the Media Foundation needs to be downloaded and installed manually. There is more information in the following article:

Fix video and audio problems on Firefox for Windows N editions

A second issue arises on sites that use DRM to control viewing and copying. Such sites include Netflix and Amazon Prime Video. More info on DRM in the following article:

Watch DRM content on Firefox

Were either of those relevant to the problem in your Firefox?
