I'll be watching a video and it will be playing properly at regular size, but when I try to watch it in full screen, all I get is a black screen. I can still hear the audio in full screen, but can't see the video.

Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

This is a mobile question amitshree. Plugincheck won't work with Firefox for Android.

What device? What video?
