Does anyone suffer from degrading image/video quality on some websites while using Firefox Android? I have this issue with Facebook. I don't want the Facebook app installed on my phone (mostly to block notifications and for privacy reasons) so I access FB via Firefox but images look terrible and every video I click opens in a separate tab instead of in-page (at least I can download it tho).

Only solution I have is using user-agent switcher to change my UA to either Chrome or Firefox for iOS (which is what I picked to keep Firefox in my UA) but this breaks other stuff on some websites.

Question is, how to get Facebook and other sites to stop serving shit quality to Firefox users? How is this fair?
