Why is There No Sound in Firefox?

If you are having a problem with no sound in Firefox, there may be a few reasons why. The first thing to do is to update your Firefox browser.

You can do this by going to the menu and selecting Help. From there, you can select Restart with Add-ons Disabled. This will allow Firefox to update without any conflicting extensions.

1. Uninstall and Reinstall

If Firefox extensions are conflicting with its audio playback, you may experience no sound in browser issue. In such a case, you need to uninstall the incompatible extensions and then reinstall them. You can do this by visiting the Add-ons and themes page in the browser.

Outdated drivers can also cause no sound in Firefox. These drivers are responsible for allowing hardware devices to communicate with the operating system. You can update these drivers by following the steps given below.

In late July, 2022, an update to Firefox version 103 rolled out that may seem to break the ability to play audio content on some websites. The new behavior requires a user interaction via a mouse click, printable key press, or touch event to acknowledge and accept audio and video autoplay – same as Chrome and Safari have required for over a year. To fix this, you need to enable Firefox to play audio without a user interaction.

2. Restart

Often times the audio missing problem is just a temporary issue that occurs when you restart your computer. Restarting your computer clears away the current state of the software and sometimes solves the problem.

In Windows 10 you can also check the audio output device preference (which is set at right click volume icon -> Open Volume Mixer > Settings -> Sound -> Advanced sound options > App volume and device preferences) to see whether it is still set to a custom value or it has become muted. If it is muted, you should change it back to Default to solve the problem.

If you haven’t updated Firefox for a while, you may face audio and video errors in new tabs. You can update Firefox by following the instructions below. Alternatively, you can use Driver Easy to automatically update your drivers with just one click. This will save you a lot of time and effort.

3. Refresh

If Firefox is the only browser that doesn’t play videos or local music on your computer, you can use the Windows Troubleshooter to check if there are problems with the audio device drivers. To run the troubleshooter, open the Settings menu. Then, click or tap the three short horizontal bar button on the top left corner and select Troubleshoot.

Refreshing Firefox resets the preferences, add-ons, extensions and themes to their default state. It also disables hardware acceleration and uses the default toolbar and theme settings. This should fix the problem if it was caused by an extension that was incorrectly enabled.

You can also try rolling back the driver updates that were recently installed on your PC if you suspect this is the problem. You can do this by opening the Control Panel and then clicking or tapping on the icon that resembles a monitor with a green background. Then, select the System and Security option and then select the Change device settings icon.

4. Reinstall

If you cannot hear sound on YouTube videos in Firefox, you might have issues with your audio drivers. Try rolling back your driver updates to fix the issue. You can do this by using the Device Manager, as described in How to Roll Back Driver Updates on Windows 10.

If the problem persists, you may have to manually reinstall your Firefox browser. To do this, you need to uninstall the old version of Firefox and then reinstall it from scratch.

Before you reinstall your browser, make sure that you do not have any unsaved documents open. You can also try restarting your computer. This will clear the cache and other settings. You can also try refreshing the browser, which will remove the extensions and themes, website permissions, Download actions, DOM storage, security certificate and device settings, user styles, and Toolbar customizations. Then, you can check if the problem is solved. This will help you get rid of the problem without losing any data.
