Mozilla plans to remove the Adobe Primetime Content Decryption Module in Firefox 52 Stable.

 

Adobe Primetime is a content decryption module that is only available for Firefox on Windows. It is designed to play back protected media streams. In other words, it is a plugin for DRM.

 

Firefox did download the Adobe Primetime plugin automatically since its introduction in Firefox 38. This changed only recently -- in Firefox 47 to be precise -- when Mozilla switched the download to on-demand only.

 

This means hat Adobe Primetime is only downloaded by Firefox when you visit a site that requires it to play back media. The change does not affect existing Adobe Primetime installations.
