Firefox Macos Big Sur

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.

1. Go to Options by clicking the menu button or the three horizontal lines
2. Choose Privacy & Security
3. Scroll and select Permissions
4. Uncheck the box for ‘Block websites from automatically playing sound’

That’s it! Try playing some videos now to see if the problem is fixed!

Another method to resolve ‘Firefox not playing videos’ is to verify that the plugin is not muted. If you have confirmed that there is no sound or the video doesn’t play, follow these steps:

1. Open the Volume Mixer
2. Check if the volume slider for Mozilla Firefox is muted, un-mute it. If it was set to low, move the slider up enough to hear sounds

• Clicking the menu buttonand then Add-ons
• Choose Plugins

Solution 6. Check Your Computer’s Audio Device

Apart from the Firefox settings, the issue may also be due to hardware problems. Often, it may not be the browser’s issue but the computer’s. 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.

Solution 7. Update Firefox

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. This update is released by the developer itself and is available for users to download and install. Firefox like other browsers automatically downloads and installs updates when it’s available.
