Downloading flv files corrupt on Firefox

[Meherr]

I downloaded a few flv files from YouTube on Firefox. There is a addon available that allows me to download the flv video files. There are some important videos which I want to download. But after that when I am trying to play I am getting a damage file error. The total size of those downloaded file is 0kb. I want a fix for the same. I want to download atleast 360p videos from YouTube so that I can view them on my tablet.

The issue can be with your plugin. Due to which you are not able to download those files. There is one more addon which you can use and it will help you to resolve the issue. You can try using video download helper. It is a nice tiny addon through which you can download the files and then use vlc to play the files. The addon can help you to download the flv file directly when you are streaming the content.

I do think there is anything better than internet download manager. This software is really awesome when you have to download video files. When you play the video you can get a tiny download button on the top side. Just click on that and select the video pixel quality and download it instantly. It works fast and it is the easiest one to use. You have to integrate IDM with your browser to get a constant download.
