Zviewer is an interesting extension for Mozilla Firefox that allows the user to access all kinds of multimedia content online, which can be channels or programs. Thanks to Zviewer you can download high quality videos (in HD) and also the usual YouTube videos.
The program installs a red button in the address bar, from which we can access the program options. Some of the channels that can be viewed from Zviewer are CNN, Fox, ABC and Cartoon Network, etc., but they are only operational for now with connections from the Internet. However, we can work with YouTube, MTV and Collage Humor.
You can free download Zviewer Beta 2 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
