Nice features that would be helpful to add:
- an option to both download and copy to clipboard
- customizable filenames (video name, video id, channel name, channel id, channel username, resolution, and timestamps in various formats)

I would give 5 stars if the download and copy option was added at the least.

Great!

so far so good! just took a screencap from youtube without the annoying as hell extra crap they for some reason won't let you get rid of on desktop, for the first time EVER. wow. it took years lmao. and automatically downloads just like that! im impressed. will update if anything changes. (unless i forget)

This extension used to work well. But not any more. When I take a screenshot, a black screen is saved. I'll have to remove the extension. I put 3 stars because it worked well in the past.

update: returned 5 stars. after reading your response, I installed it again and it's working now. Thanks!

Genius!

Sometimes you have to enable-disable to make it work but still it is pretty good with its filenaming, a key shortcut would be cool though.

good screenshots file names. same as page title

It works just like you expect. A small nifty useful tool. Thanks a lot.

Baš ono što trebam! 🍻👌

Great extension, very easy to use, the code is public and you almost collect no data.

The only thing is that the size of the "screenshot" depends on the video size on the screen instead of the resolution. It is good when a video is of low res, then I can still get a large picture without needing to zoom in.

However, if a video is of higher resolution than my screen (more than 1080p), then there's no chance for me to download the full res frame.

Therefore I'd propose to give users a choice between a screenshot (literally, as it is now) or a frame download.

Quick and easy. If only there was something similar for all video sites...

Amazing... 1 click screenshot for YouTube... Handy if there are graphs or tables you want to capture in a video...

Thank you <3

works well in PiP mode. but latest version can save only jpeg, can't select PNG.
I'll use old version.

I lowered my rating by one for the following reasons.

1
Even with the video quality set to 1080p, the size of the screenshot was not 1920x1080.
The size of the screenshot seems to be determined by the actual size of the video on the screen, not the quality setting.
Note that in the case of a similar extension for Chrome, the size of screenshot is determined by the quality of the video, not the size of the video displayed on the screen.

2
Conflicts with Enhancer for YouTube.
If Enhancer for YouTube is enabled, the screenshot button will not appear.

Good add-on, just doesn't work for playlists and queues though, you need to open the video indivually to be able to screenshot it.

I love it, but it doesn't work if the video is a part of a playlist I have to copy the video URL from the share button and open it again
