可以用，可以录到声音，使用也很方便，缺点就是分辨率低。致命问题是不能录到全部片段，例如：录一分钟的视频，只能播三秒钟，后面就直接没有，文件大小也是够一分钟的，却只能播放三秒钟！用剪辑软件打开，所有内容都是可以播放的！

This is one of the only addons that AUTOMATICALLY captures video streams at the "source level", eliminating the need to fuss with capture areas, window sizing or frames to record just the video. It's not a screen recorder, per se, so the user can surf the net while video capture continues in the background. The problem is, I've noticed significant 3d noise ("grainy" picture) when playing back recorded videos. It's not a hardware shortcoming. Also, there's no toolbar button to toggle recording. The user does need to be on the video page to start or stop recording. However, once the "stop" button is clicked, the video is downloaded without any further user interaction, which is super, super handy.

It worked great for over a year - been using it since lockdown. However, there has been some problems lately and the recording stops after maybe 30 mins. I'm using it for online classes, and I miss out the rest of the lesson. I get an error that says "unlucky error". Hope the developer will see this review and help fix this bug. I've tried to email him but the email bounced.

I like this but it didn't work correctly as intended. I received this warning when I clicked on record "Security error: open the video in its own tab. Open in new tab" I did as recommended and it downloaded the recording to a file. it was a big file 1.1GB as the recording was 3h but the recording worked so I'm happy about that.
I tried it again though and this time it didn't work. I stopped trying after that but will give it another try on some other recordings to see how it work on those.
thanks for developing it it has worked better than most others I have tried.

Hello,
I have recorded a radio audio stream (about 1 hour) and then I tried to download the file. Now it's stuck at the recording icon and seems not to respond.
I have not used the Preview button
