Been having a issue for a long time were if I watch live youtube videos
the browser would start taking up a ton of memory and start becoming really slow

finally figured out that disabling this addon made that problem go away

Очень удобная программа , я много пробовала программ но эта самая надежная , быстрая и некогда не подводила меня спасибо вам огромное

Una excelente opción para capturar videos en Youtube!!

Been using for years,,, BEST DOWNLOADER EVER. Don?t believe the bad reveiws... need to download companion app to use it and then it works great!

very good

dysfunctional without payment - how is it possible that this is not mentioned in the profile on mozilla's page??

מעולה

This is very reliable , faster and efficent app for downloading videos. Even though initially it requires to install the supported software but after that it is super efficient in downloading any videos. Highly recommended app to have.

很好用

Bit of a process to get set up. Requires a local app to work along with the extension. However, has probably the most powerful capability as a downloader I have used. Would recommend!
