On Windows ARM, we currently use the x86 version of the clearkey plugin. We do however ship Firefox with the ARM version although prior to this patch it was unused. Now if media.gmp-clearkey.allow-x64-plugin-on-arm64 is set to false, then we will attempt to load the ARM version of the plugin. The pref remains true by default.
