The Mozilla Foundation created Firefox as an open-source and free web browser. But while streaming on your browser, it may have displayed the message no compatible source was found for this video in Firefox. In this article, we will cover all possible fixes.

Despite Firefox’s robustness and impressive feature list, you may often encounter errors streaming videos on the browser. For example, you may have problems playing DRM-protected video from Hulu, Netflix, Disney+, Amazon Prime, and other streaming services.

Additionally, the error code 102630, when videos can not be played is just another common streaming problem you may have.

Firefox’s compatible source error is similar to the non Chromium browser’s error of where the video file cannot be played.

So, let us get to it.

What video formats are supported by Firefox?

Because patents control some music and video file formats, third-party programs are essential to use them. However, Firefox can play open as well as patented media natively.

Firefox Open Media

The Firefox browser is able to play uncompressed audio stored in a WAV container format (.wave,.wav file formats).

Additionally, Opus audio, Vorbis audio, VP8 video, and Theora video are open-source audio and video compression standards that are free to use.

These standards are used in the Firefox browser once they are encoded in the WebM (.webm file format) or Ogg container formats (.ogg, .ogv, .oga, .spx, .ogx, .opus).

MP3 playback (.mp3 file type) and FLAC  playback (Free Lossless Audio Codec) are also supported by Firefox.

Patented media

The audio and video reduction formats H.264 or MPEG-4 AVC and AAC are patented. 

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

But, using the in-built OS libraries, they may be displayed in Firefox. So, if they are incorporated in any MP4 container format, neither Mozilla nor you will have to pay a charge to view them.

When you get an error message that no compatible source was found for this video in Firefox, you may consider using another browser to connect to the service.

While a reinstallation may fix this error, it will persist on Firefox in some cases. However, it may be a specific problem between Firefox and the streaming service.

We love to recommend Opera because it is robust, widely used, and popular among many big platforms, so it offers easy integration widgets to many of these platforms.

Additionally, it offers a built-in VPN which means that you will be able to access streaming services and videos without exposition your IP address or location.

⇒ Get Opera
