YouTube Not Working on Firefox 2017 Solutions

Having trouble accessing YouTube on Firefox? Here are some solutions to get it working again in 2017.

Enable Safe Mode and Refresh

To troubleshoot YouTube not working on Firefox, you can try enabling Safe Mode and refreshing the browser. This can help identify if any extensions or add-ons are causing the issue.

To enable Safe Mode in Firefox, follow these steps:

1. Click on the Menu button in the top-right corner of the browser window (three horizontal lines).
2. Select “Help” from the drop-down menu and then choose “Restart with Add-ons Disabled.”
3. A pop-up window will appear, click on “Restart” to confirm.
4. Firefox will restart in Safe Mode, which disables all extensions and themes.

Once in Safe Mode, try accessing YouTube again. If it works fine, then an add-on or extension could be the culprit. To narrow down the cause, you can go to the “Add-ons” section in Firefox and disable them one by one, checking YouTube after each disable. This will help identify the problematic add-on.

If enabling Safe Mode doesn’t resolve the issue, try refreshing Firefox. This will reset the browser to its default settings without affecting your bookmarks, history, and passwords.

To refresh Firefox, follow these steps:

1. Click on the Menu button and select “Help.”
2. Choose “Troubleshooting Information” from the drop-down menu.
3. On the Troubleshooting Information page, click on the “Refresh Firefox” button.
4. A confirmation pop-up will appear, click on “Refresh Firefox” to proceed.
5. Firefox will close and reopen with default settings.

After refreshing Firefox, check if YouTube is working properly.

Manage Add-ons and Autoplay Settings

1. Open Firefox and click on the three horizontal lines in the top-right corner to open the menu.

2. Select “Add-ons” from the menu to access your installed add-ons.

3. Disable any add-ons that might be causing conflicts with YouTube. To do this, click on the add-on and select “Disable” or “Remove” if necessary.

4. Ensure that you have the latest version of Adobe Flash Player installed on your computer. You can download it from the Adobe website if needed.

5. To enable HTML5 video playback on YouTube, visit and click on the “Request the HTML5 player” button.

6. Clear your browser’s cache and cookies by going to “Options” > “Privacy & Security” > “Clear Data”. Make sure to select both cache and cookies before clicking “Clear”.

7. Check your Firefox settings for any specific autoplay settings. Type “about:config” in the address bar and search for “media.autoplay.enabled”. Double-click on it to set it to “false” if it’s enabled.

If you want to downgrade your Firefox version, you can find older versions on the Mozilla website. Here’s how:

1. Visit the Mozilla website and search for “Firefox release archive.”
2. Click on the first result, which should be the official Mozilla page.
3. Scroll down to find the version you want to download and click on the corresponding link.
4. Once the download is complete, open the installer and follow the on-screen instructions to install the older version of Firefox.

Remember to back up your bookmarks and other important data before downgrading.

If you’re still experiencing issues with YouTube on Firefox, try the following solutions:

1. Update Adobe Flash Player: Make sure you have the latest version of Adobe Flash Player installed. You can download it from the official Adobe website.

2. Enable HTML5 video: YouTube supports HTML5 video playback, which can be more stable than using Adobe Flash. Go to YouTube’s HTML5 page and click on the “Request the HTML5 player” button.

3. Disable Adobe Flash: If you’re experiencing issues with Adobe Flash, you can disable it in Firefox. Type “about:addons” in the address bar, go to the “Plugins” section, and click on the “Disable” button next to Adobe Flash.

4. Clear cache and cookies: Clearing your browser’s cache and cookies can help resolve various issues. Go to Firefox’s menu, select “Options,” go to the “Privacy & Security” tab, and click on the “Clear Data” button.

5. Try a different web browser: If the problem persists, try using a different web browser like Google Chrome or Internet Explorer to see if YouTube works properly.
