1900173 - Nvidia VSR doesn't work with MS Store Firefox

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect)

Description

[gybeom8008]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

1. Play any Youtube video on MS store Firefox, on any profile

Actual results:

RTX video enhancement appears 'inactive' on Nvidia control Panel

Expected results:

VSR immediately appears 'active' on Nvidia control Panel

It works on normal installer version Firefox, so I guess the problem is with the MS store version.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

If you compare the "Media" and "Graphics" sections of about:support between MS Store and regularly installed Firefox versions, what differences do you see?
