Solution 1. Allow Autoplay of media with sound
Unlike Chrome, Firefox, by default, blocks the automatic play of all media with sound. This might be one of the reasons why you cannot play videos on this browser. This change happened only after the latest Firefox update. The recent Firefox update made this change due to so many reports that websites with video autoplay when opened even when they are not necessary. Most of which are Ad videos which can be annoying to hear and watch. With the recent block, the videos will continue to play without sound.
Some users reported that after the update, they were not able to play any videos on YouTube, Facebook, and even on other websites. This is not a system glitch; in fact, it’s a new feature that you can simply customize according to your preferences. You can turn on the sound by clicking the Block Autoplay Control Center (the icon looks like a circle with a small letter i in the center) beside the URL bar. Click on the drop-down arrow in the Permissions section and choose between Allow and Block.
Another method to allow autoplay is to go to the Settings.

Check if the audio device you are using (headphones and speakers) is turned on and properly connected. If you are using headphones, make sure that the cables are well connected to avoid any audio problems. Also, verify that the sounds are not muted on the volume control.

If your issue is prior to the recent Firefox update, it might be caused by bugs and can only be fixed with a new update.

However, if you would like to, you can manually update or check for updates on Firefox by going to the ‘About’ window and then clicking on the Help menu. Select 'About Firefox' to update.
