Youtube and WebMs are weird when trying to automatically play (details inside), yet using Flash to load videos on sites like DailyMotion works fine.

This started a few days ago, possibly coinciding with updating to 41.0.1.

If I load a video on Youtube, or load a WebM, the video shows that it's set to "play", as it's supposed to, and it loads as normal, but it doesn't actually play, the time just stays at 0:00. If I pause and unpause it, or move the timer, it plays like normal. Also, if I load a Youtube video from a referral link on the page of a video I'm already playing, this doesn't happen. This also doesn't happen on sites like DailyMotion that only use Flash instead of HTML5.

Is there a proper fix for this? Even if I were to force Youtube to play with Flash instead of HTML5, it won't fix the problems with WebMs.

My Extension setup is the following:

  • Custom New Tab 2.1.1
  • Dictionary Extension 3.0.12.1.1
  • Download Manager Tweak 1.0.9.1
  • Download Youtube Videos as MP4 1.8.3.1
  • DownloadThemAll! 2.0.18.1
  • HTTPS-Everywhere 5.1.1
  • Mega 3.1.19
  • NationStates++
  • New Tab Override 1.0
  • NoScript 2.6.9.38
  • Ratings Preview for Youtube 4.1.2.1
  • uBlock Origin 1.2.1
  • Undo Close Tab Replacement 8
  • Youtube mp3 1.0.9.1

My Plugin setup is the following:

  • OpenH264 Video Codec by Cisco - Always Activate
  • Primetime Content Decryption Module by Adobe - Always Activate
  • Google Update - Ask to Activate
  • Java Deployment Toolkit 8.0.600.27 - Ask to Activate
  • Java Platform SE 8 U60 - Ask to Activate
  • Microsoft Office 2010 (Officer Authorization) - Ask to Activate

Did you disable autoplay in the HTML5 media player or have an extension that blocks media files?

You can check this pref and other media prefs on the about:config page:

  • media.autoplay.enabled

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

I agree with cor-el's diagnosis. Before Firefox 41, scripts would send a Play command to the HTML5 media player to start the video to work around users who disabled autoplay. Firefox 41 stops the playback, but it does not fix the player controls, so you see a pause button even though the playback is halted. Hopefully there's a way to fix it in a future update.
