Twitch Stream Not Working on Old Firefox: How to Fix
In this guide, we will show you the steps to fix the issue of Twitch Stream not working on old Firefox. Many users have voiced their concern that the Twitch streams play audio just fine but show no video; it’s just a question mark on the screen. Even when an ad plays, it’s just an audio with no video.
The issue only seems to impact older Firefox versions, including the Extended Support Release (ESR) versions, especially on Windows 7 OS. Fortunately, we found the reason for this issue and, more importantly, the fix as well. So without any further ado, let’s get started.
Why is Twitch Stream Not Working on Old Firefox
The reason behind this issue is the fact that Twitch recently updated its website and added a CSS feature called the “ has() selector”. Unfortunately, this selector isn’t supported in older browser versions. As a result of this, the video player’s width is set to zero instead of 100%, leading to no video on the screen.
