No detecta las ventanas para seleccionar la que quiero grabar

可以录到原始画面，我的1080P全都能录到，可是没有声音，也找不到在哪里设置。

it doesn't work. it only records a black screen

This Add On has never worked for me, it only records a black screen, the desired video doesn't show up when hitting the available screens.

Для меня приложение оказалось бесполезным, хотел сделать запись с активной вкладки, но вопреки своим желаниям технические возможности данного приложения не дали осуществить задуманное. Пожалуй пойду выпью винца..

It works for me! I don't need audio.

It is okey to use. I don't want audio so it is okey. But if you need audio, this is not the addons you need.

录制的视频没有声音

It record video very well, in .webm, but that's it. No audio, no options except start recording, stop recording and save. Should've been more clear i think, since i downloaded in an hurry to save a meeting, but turned out useless since no audio was recorded. Stay away unless you don't need audio recording.

Audio recording no longer supported on firefox?

no hace lo que uno espera, si dice grabador de pantalla y es lo único que hace, no graba audio, no da tiempo de preparar la pagina del video, le faltan herramientas, como ocultarse el mouse y la barra de grabación y se traba mucho de 4 intentos dos
