Great extension but sometime, there are 2 videos playing after clicking. Try this page : https://fr.news.yahoo.com/video/dauphin-sauvage-veut-faire-gratter-143007674.html

On some site, it doesn't work, there is only the sound. Italie : de violents orages ont coûté la vie à au moins dix personnes dans la province d’Ancône https://is.gd/2of9Qo

5 stars if you can hide the red frame. It's in the way in most cases but the extension does what it is supposed to and it's the only one i can find that does it for all sites.

Great add-on that works well. A nice feature to add would be the ability for the end user to be able to hide the red frame, because for me it is quite distracting.
Thank you for all your effort.

Thanks for this Firefox add-on, ArsTech's b***s**t auto-playing videos were just out of control.

EDIT: Can you add a configuration to toggle off the click to play and play icon? It obstructs the view on small thumbnails and videos.

As opposed to other similar addons, yours actually show a "preview" image. Which I love. It also solved Firefox abnormal high CPU usage issues I'm having on some sites. The only reason I didn't give 5 stars is because there is no toggle button on the toolbar.

This really works - always stops the video running - Great.
Two whinges
1/ - The red box usually doesn't line up with the video so it can get in the way of other interaction with the page - I'd probably try to fix it if I knew a bit more, but I'd need some guidance
2/ - I'd now like to be able to disable it on specific websites

This is the third one I've tried, and the first one that will actually block the new autoplay on a YouTube channel home page. It's not perfect (the red frame ends up above the channel home page autoplay video, instead of around it), but at least it works.

(Were these YouTube people born in a barn? What were they thinking? Finding ways to bypass browser settings and force autoplay? Don't they have better things to do? Don't they have the slightest understanding of netiquette?)

This works 100% of the time. Unfortunately some sites it works too well. There are some video sites, like Netflix and Amazon, where I wish I could white list those sites to they will operate normally. DAP messes up NF and AP and to get them to work you have to disable the extension.

Very effective in blocking auto play in audios and videos. The video will play only if you click the "click to play" option. So far so good. Thanks.

works but yahoo has been wising up.now theres times when u will click one vid to play and another square remains in the same area..and if u click that square to make it go away another vid will start playing..
this does its job of not having things not play automatically but could use a lil adapting to the new annoying things that are coming our way

Very nice in comparison to similar addons as it's easy to see which vids were stopped.

Some cusotomization would be welcome though - i.e. toolbar button with on/off toggle and a site black/gray/whitelist (surely, all of this code can be copy/pasted from an open source addon, if you release the source code yourself?)

Works for the most part. My configuration is (Windows 7 Home Premium + Latest version of Firefox).

When an YouTube Video page is being loaded, the video is successfully blocked from playing automatically.

However, the downside is, once we click the red box (that this add-on overlays on top of the video) and make the video play, the add-on does not seem to work when we click and open a "suggested video" that is displayed on the original video's page. Hopefully the developer could sort this out. I will increase the Star Rating to 5 once this issue is taken care of.

Steps to recreate issue:
1) Load any video on YouTube
2) Click the red box displayed on top of the video to make the video to play
3) Now click one of the suggested videos displayed on the right side of the original video's YouTube page (Or, after the original video you opened completes playing, click on one of the suggested videos displayed on the Video Player).
4) The suggested video will load, but this time the add-on fails to kick in. This video still automatically plays.

Workaround for the time being:
In step #3 above, instead of directly clicking on any of the suggested videos, open the suggested video in a NEW TAB (by right clicking and selecting 'Open link in new tab' or by pressing and holding the 'Control' key in your keyboard while clicking). Now the add-on kicks-in in the new tab as expected and stops the auto play of the video in the newly opened tab (even if the video on the original tab is still playing).

This is a very good idea, especially considering the dearth of HTML5 Autoplay-blocking add-ons in the Firefox landscape. The only thing I am badly missing here is a whitelist; please, dev, could you consider adding one in a future update?

Many thanks for your efforts.
