Works very well!

Not perfect (had some glitches) but the only extension that I've found that actually offers a whitelist approach. I verified I can block on sites like CNN and can allow on sites like youtube & netflix. This should be built into browsers period and on by default. I can think of no good reason of ever wanting to allow this by default. So, good work.

Most of the time doesn't work.

Does not work in Netflix.

Woeks great. Thanks!

Haven't had a single problem with this add-on, honestly works even better than I expected. Very well done.

It's very simple. It does exactly what it says that it does. It works perfectly.

Sometimes works, sometime not.

Mimics the diasabled media.autoplay.enabled setting in about:config but provides a needed whitelist.

It's been working well. Thank you.

I can't disable totally for a single url

OK.

Thank god for this. I was getting really annoyed with my capped bandwidth being sucked slowly through my modem because of video I didn't request. Works great for HTML5. It just puts a play icon on top of the video without starting it. You don't lose anything. Great work.

Buggy. Options don't change with mouse clicks, appear twice and have no effect.

не работает

So far it has stopped the videos from automatically running which has frustrated me since I moved to a Windows computer.

Funcionou perfeitamente pra mim. :)

nice, easy and works very well
