CoApp Installation

Some operations required by Video DownloadHelper cannot be performed from within the browser. In order to be able to still do the job, the add-on relies on our external application that is called transparently. We call it the Companion Application (CoApp).

The Companion App is an Open Source software. You can find the code here.
