Fix No Video with Supported Format and MIME type found
What causes the No Video with Supported Format error?
Ever since the arrival of HTML 5, media errors on the internet have become common. After Adobe flash player was discontinued, HTML 5 became the ideal replacement. Being a safer and faster markup language, HTML 5 is highly sensitive to issues on your PC. These include outdated browsers, corrupt cache files, and intrusive extensions. Luckily, the “No Video with Supported Format” error can be fixed with a few easy steps.
Method 1: Update Firefox
Playing videos on outdated browsers is a challenging task. Many times, older versions are unable to register new media encoders and struggle to play videos.
1. Open Firefox and click on the hamburger menu in the top right corner of the screen.
2. From the options, select Help.
3. Click on About Firefox.
4. A window will appear on your screen. If your browser is not up to date, you will get the option to download the latest version.
5. Play the video again and see if you’re able to fix No Video with Supported Format error.
Method 2: Clear Browser Cache and Cookies
Cached cookies and data can slow down your PC and cause unwanted errors. Moreover, corrupt cookies prevent sites from loading media files which results in the “No Video with Supported Format” error.
1. Open Firefox and select the hamburger menu
2. Click on Options.
3. Go to Privacy and Security from the panel on the left.
4. Scroll down to Cookies and Site Data and click on Clear Data button.

Method 3: Disable Browser Add-ons
Similar to the extensions on Chrome, Firefox introduced Add-ons to make browsing more fun. While these services can enrich your online experience, they interfere with online activity. Try disabling a few addons to fix the “No Video with Supported Format” error.
1. Click on the hamburger menu and select Add-ons and Themes.
2. Go to Extensions from the panel on the left.
3. Find the extensions that could cause errors during playback.
4. Click on the three dots and select Remove.
5. Reload the website and see if the video plays.
Method 4: Use Another Browser
While Mozilla Firefox has done a commendable job over the years, it has not caught up with the speed and efficiency of Google Chrome. If all the aforementioned steps fail, it is time to bid adieu to Firefox and try other options. On your browser go to Google Chrome’s installation page and download the app. Your videos should run properly.
