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.

works like a charm

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

working on youtube and other background videos like adds on sites.

}{ерня нерабочая.

Excellent add-on. Solved annoying issues with autoplay videos

can't whitelist sites

Thank your very much!! Useful plugin

Doesn't work on all sites. One website had a youtube video embedded and it auto-played behind the red frame. Also doesn't play nice with youtube.

doing exactly what I wanted. Stopping the annoying videos auto playing on WaPo and The New Yorker. That's all I've tested it on so far.

Thanks for this!
Successfully disabled autoplaying videos on web sites where others failed.

Just giving a pink border on the video window doesn't mean its blocking it. The auto load or autoplay video already loads few seconds on the page. The pink border is annoying. This should have blocked all flash and autoplay auto load videos like image blocker blocks images. It does not work ; the video auto loads.

Good alternative to Mcafee Web Boost

Can it stop preloading?
It stops the stream/video yes but there's a 'pic' of what the stream/video is.

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.

tried to use on Tubi, it breaks Tubi. It puts a red block around the video, says click to play and does nothing. I suspect this option is being used in the config file: media.autoplay.blocking_policy (2) which prevents Tubi from functioning.

Work like a charm in firefox 81 on ubuntu unity 20.04. Well done! Keep it simple!

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

Great tool overall, but could you please add Allow list, as it needed for some sites. Thanks
