Doesn't work, unfortunately.

The extension works inconsistently.

Finalement un moyen efficace de bloquer les vidéos sur yahoo qui se lancent toutes seules, que ni le réglages du module Flash, ni le passage en "false" du media.autoplay.enabled dans l'about:config de Firefox ne géraient...
Merci !

Works like a charm! Thanks

No matter what, it'll always prevent a page from preloading. Even when you set a page to preload. Which prevents proper use of Youtube.

It works MOST of the time with YouTube. I usually have to reload the video page for it to kick in.

Worked great for the most of 2018. Then the videos started autoplaying again... CNN, ESPN. Uninstalled today and am currently using another autoplay disabler

Doesn't work for me. It's a shame there is only one app to choose from. Opera/Chrome offer several.

Add-on works, it stopped autoplay on iz.ru)

Causes many video streams to fail, throwing the following JavaScript error: "This video cannot be played due to a technical error.(error 200001)"

I'm using waterfox, the add-on works by stopping the htm5 video autoplay, but it doesn't stop video buffering, I can live with this limitation, but the biggest issue that made me uninstalling the add-on is the add-on somehow lags the browser when enabled. FYI I have multiple tabs opened with tabmixplus add-on. Also, the toolbar button UI is a bit buggy (maybe it's waterfox compatibility issue)

Works great with CBS News autoplay video.

Since Firefox 66 released, Firefox can disable HTML5 autoplay by default on all platforms.

Unfortunately, this add-on is not doing anything at all for me in Firefox 65.0.2 on Windows7 64-bit. I like how it has options for both "autoplay" and "pre-loading" and that it is designed for all HTML5 video sites.

Other reports suggest that it works for some people, but not for others. Too bad, as the concept is useful and the interface is well-designed.

Just installed it 30 minutes ago & it seems to be working well for me on Yahoo Finance.

Ne fonctionne pas sur smallbusiness.chron.com avec Firefox ESR.

I'm using Firefox Nightly 67 64bt on my Windows 10 October 2018 laptop. And the add on does not work at all on YouTube and... any other sites.

It works but where's the source code you "licensed with X11"?

I'm thrilled to say that, to date, this works exactly as described--including Youtube videos. What a relief. While it would be very nice to have a whitelist, I have not found it too distracting to have to click once to get a video started.
