Camera motion causes Edge to disable extension

This is a great extension! It does what it is supposed to do. There is one problem with this extension though. When camera motion is activated, going to a site that this extension works on causes Edge to disable the extension. The only fix is to keep camera motion off and use the extension normally by clicking it or using the autoplay feature.

Willing to change rating if extension will appear

I'm sure it's a great extension based on what I've seen of the browser, but my browser informs me that I'm full of it whenever I try to say that I have the extension, and the Store is the only one that believes me. If it ever appears in my browser I'd be happy to change my rating once I try it out.

Works very nice on youtube, but it would be great if it can be set to be automatically dim the lights when playing videos.

The button just isn't even there

Latest version of Win10 and it's not even coming up in the list of extensions so I can't even uninstall it.

Tab freezing with HTML5 players e.g. twitch

It seems that when this extension is enabled, while watching videos that use an HTML5 player, the tab starts to become unresponsive and eventually freeze. Update: Just to add, no other extensions are enabled and TOtL is using its default settings.

Will give it a try

I often find pages rather bright and like the functionality to dim them without affecting my brightness. Since I use a laptop, I scroll using the touchpad. I found it glaring that when a page is slightly scrolled out of, the revealed section is undimmed. Would you consider widening the dim margin for those of us who are able so scroll out of the ordinary screen?

kills sound control

Muting is not reversible as controls disappear. Turning off extension fixes this.

Stopped working for no reason

Was working fine but for some reason it constantly turns off so I randomly get blasted with pure white light from webpages. Fix this problem!
