Videos: start playing not before one opens their page?

Dirki · Post by **Dirki** » February 13th, 2019, 12:30 am

I have exchanged the newest ESR Firefox with the newest nomral Firefox. Now, when I open different youtube videos by clicking them on one page they start to play in another page instead of not starting to play like it was in ESR. They started playing when one clicked the tab to show the videos. How could I make the normal Firefox doing it like that?

Between that issue and your issue with multiple tabs closing ( http://forums.mozillazine.org/viewtopic ... &t=3046844 ) when you go to close one tab, sounds like you have one screwed up Firefox installation!

My advice is to start with a clean sheet (fresh installation and a new Profile) or do some troubleshooting using the Firefox SafeMode.

So the starts of the vidoes and unwanted multiple tab closes might hint to a screwy Firfox.

I use portable ones. How could I transfer my data (bookmakrs, settings and such) to a fresh Firefox?

do some troubleshooting using the Firefox SafeMode

How could I do the troubleshooting there?

The videos playing is the way the autoplay setting has changed in current Firefox. Before, autoplay was blocked by setting media.autoplay.enabled to false. Deprecated.
Now to block autoplay, in about:config set media.autoplay.default to 1 .
You may also have to set media.autoplay.allow-muted to false .

On two different occasions I've had to refresh FF 66.0.2 because at random New Tab Video Auto-start will not play a video. I've changed the about:config, media.block-autoplay-until-in-foreground from true to false. With false selected the video will not auto-play. I'm running AdBlock Plus, Video Download Helper and YouTube Video Downloader. I've run FF in safemode and the issue still persist.

***Edit*** Just noticed in the URL bar (site information button) there is an option there to Enable or Disable Autoplay. Very nice and convenient.
