I am using the latest nightly build of firefox, (alpha) on debian/gnu linux. whenever i play a video there i get this ONE line of code error in my console window that i run firefox with.

this: Child 32560, MediaPlayback #3] WARNING: Decoder=7f50f3807880 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr<mozilla::MediaTrackDemuxer::SamplesHolder>, mozilla::MediaResult, true> > mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /builds/worker/workspace/build/src/dom/media/MediaDecoderStateMachine.cpp, line 3411 </p>

this is just one line of code that messes up. as you can see its a fatal error but nightly keeps running.

any information that is needed i can supply with a comment if need be, i don't have the source so i cant look at line 3441

thank you ~wes

Looks like a lot of things not working like about 3/4. Please reinstall your drivers. Is nothing on Firefox's end that can help.

Please let us know if this solved your issue or if need further assistance.
