I disabled one didn't work so enabled and disabled the other still didn't work also tried disabling both didn't work. The above method by Firelord didn't work for me ( should work for older Firefox versions & useful if the extensions aren't available for your Firefox version ) If the video buffers, if you're getting pop-ups when playing video. Changes would take effect immediately, else, restart Firefox. Agree for any warning or agreement if you happen to come across. Reasons why you'd want to use a different video player. Launch Firefox and enter about:config in the browser.

) I used Firefox 54.0.1 which is the latest Firefox atmįor desktop I saw this which I'm not sure if it works but from the look of the reviews it does. ( go to the website find the video but dont tap play instead open the firefox menu and select "play video externally" Firefox should ask which player to use select one I've tried this with VLC & MX Player both worked. You can choose "Just Once" or "Always" for an app shown there. Now whenever you would attempt to open any of the file with said extension you would get a dialog with names of all the apps that are registered to play that file.

Thankfully, Firefox didn't choose to hard-code this behavior in its code so we can still change it. At least for these two extensions Firefox would play the file in its default player rather than giving you the option to choose an external app to play that file.

I don't stream videos using mobile browsers but I guess MP4 and WEBM are still the most common formats used by websites.
