This version came with some problems about stream download in periscope web. Duration of live videos is not correct and so it losts the beginning part of the videos.

Slow and desperately needing rename file function. Okay though. Works on hard to download files

When clicking "download" on a video, often the file dialog opens but remains empty. Closing and clicking again on download (sometimes up to 3-4 times) is required to fix the problem. This is highly annoying – please fix it.

It's a great app to download videos. There's only one flaw: when the extension is enabled and you play a live stream on Youtube, the CPU usage goes to the roof. I have to disable it and reenable it when finished.
It also works on some sites but not in others. In many of them the video is jagged and you have to pay to fix it
