content: The last week or so, youtube doesn't work properly when logged in with a specific account. If I am not logged in or I am logged in with accounts different from the "problematic" one everything is just fine.Upon choosing to login with the specific account, youtube page will hang for a while (A web page is slowing down your browser). After finally the login process completes, I can only play videos opened from the youtube front page. Opening a video in a new tab for example will crash the youtube page and the video doesn't play.A video demonstrating the issue:https://youtu.be/OJ2KPc821ZoI have tried everything. Cleaning cookies, cache etc. The problem even happens with a brand new profile in safe-mode.It evens happens on a different machine (I have never used) running Windows 7. What part of my account makes Firefox behave this way?Latest version of Firefox 61.0.2 (64-bit) on ArchLinux.All other browsers function properly (Chome, Chromium, Konquerror).How can I debug such a problem?When the pages stops this is the error on the console:Code:!!!  Error: PClientSourceOp::Msg___delete__ Route error: message sent to unknown actor ID!!!  Error: PClientSourceOp::Msg___delete__ Route error: message sent to unknown actor ID[Child 20461, MediaPlayback #3] WARNING: Decoder=7f49ea87b2e0 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::mozpromise<refptr&lt;mozilla::mediatrackdemuxer::samplesholder&gt;, #1]="" #2]="" #3]="" #4]="" &gt;="" (0x806e0005)="" -="" 20461,="" 3411="" <="" [child="" build="" decode="" decoder="7f49ea87b2e0" detached.:="" dom="" error:="" file="" firefox="" is="" line="" manager="" media="" mediadecoderstatemachine.cpp,="" mediaplayback="" mozilla-unified="" mozilla::mediaresult,="" mozilla::mediasourcetrackdemuxer::dogetsamples(int32_t):="" ns_error_dom_media_fatal_err="" p="" refptr<mozilla::mozpromise<refptr&lt;mozilla::mediatrackdemuxer::samplesholder&gt;,="" src="" true&gt;="" warning:=""></mozilla::mozpromise<refptr&lt;mozilla::mediatrackdemuxer::samplesholder&gt;,>

content: from time to time something in the firefoxaccountprofile craps out and youtube stutters, AFAIK the only solution is to save all that is to be saved (or just use firefox sync), delete profile, create new profile and import everything in the new profile

content: Doesn't makes a difference. I even tried it on a machine with a diferent OS with a fresh install of Firefox. When logging in with my specific youtube account, youtube stops to function properly.Alexander.

content: Quote from: GlennSprigg on August 24, 2018, 02:35:18 pmIn your opinion. The OP asked for how to fix Firefox, not how to change to another browser. He has already reported that other browsers work fine, and it is a specific issue with FF. He also reported he is running ArchLinux which avast do not support.Quote from: firewalker on August 23, 2018, 11:50:11 amI have seen this before but in Chromium, the cause was a buggy video driver. If you're running a recent AMD card, try an updated kernel, if nvidia perhaps try the binary driver or update it.

content: Have you tried disabling hardware acceleration? I don't use Firefox but from memory it's under Options > General > Deselect "Use recommended performance settings" > Deselect "Use hardware acceleration".On some system it fixes video glitching.

content: Yes I have tried every combination. I use Intel 3000 gpu.It must be a script with a specific option for the specific account. It work normally with any other account I have used.I don;t believe it hardware problem, because when login finally completes all the videos play fine if opened from the youtube first page, or if the video is embedded in a forum. It will fail when opening a video to a new tab or window. And also the problem is present in any computer I tried. Regardless of OS and hardware.Alexander.

content: I recall Youtube are now using a javascript library, a small part of which doesn't work at all in Firefox.Google would rather people use their browser, and so aren't that interested in fixing it.
