Yes I have dark reader add on and ublock origin, I used to have YouTube high definition add on but it didn't do anything,, it's very confusing since the videos do work in 1080p on my computer but on my phone I get 720p...i get some videos in 1080p on my phone but it's rare.

That's a link to a YouTube video that outputs 720p on my android phone using Firefox browser but on my computer (Firefoxbrowser) outputs 1080p. Not sure if that's what your were referring to... Thank you

I tried this link and this is what I found. On my computer (using Firefox), 1080p is not available. However 1080p60 is available. On my phone, it does not give me the option of 1080p60, but 720p is the highest.

If I go to another video which offers 1080p on my computer (not 1080p60), my phone will be able to play it in 1080p.

So it seems that Firefox for Android does not offer 1080p at a 60 fps rate, where it does work with a 30 fps rate.

Sorry for the late response. Thank you for taking your time to help.

", where it does work with a 30 fps rate" Your saying that whenever there's a video in 1080p on Android/Firefox it's in 30 frames per second? So it's all about what the video is uploaded in? For instance the same video I linked, if the person would have chosen 1080p(not 1080p60) then I would be able to watch it in 1080p 30 frames per secondon androi/Firefox? Sorry for my bad English. .. Thanks in advance

Hello

If it seems that only videos in 1080p 30fps are working on your mobile browser, the issue may lie in your device's video playing capabilities. Try checking if you can play a 1080p 30fps video, if you cannot, try a different browser and see if that works.
