Mozilla has fixed a playback issue on YouTube that affected some Firefox users for several months.
Some Firefox users noticed playback issues on YouTube for several months. These affected high resolution videos only, from 1080p and up. To make matters worse, no clear pattern could be identified.
Some videos played fine, others would stop abruptly when they ran out of buffer.
It seems Netflix is able to detect that spoofing, and sends this error when trying to play videos, "Sorry, something went wrong. Please try again later.". I had to disable my add-ons one by one to identify that it was User Agent Switcher causing it.
Simple solution is to not pay Netflix and just pirate their content. They go out of their way to make the experience worse for paying customers on a regular basis. Sonarr+Jellyfin on an old computer with no video card and you've got a better Netflix where your content doesn't just magically disappear or fail to play on some devices.
This ends with $500/mo Netflix subscriptions. An employee comes to your house and holds a laptop up in front of your couch while looking for hidden cameras camming the show.
Bathroom breaks are allowed, but they’ll pause the show.
The DRM module tells Netflix you are on Firefox. For Netflix I would use Chrome on Wine tbh, it now supports 1080p w/o extensions. Or maybe Chromium w/ ChromeOS' Widevine module + CrOS user agent.
When it all goes down, there's always the option of just downloading what you want to watch and watch it in your favorite media player. That's what I do on my phone since I refuse to watch ads and they make everything buffer. Hit the dl button and in under a minute i have the video downloaded in hd.
