Another way to make the video downloadhelper companion app safe to use is to install the Google Chrome version, which has become the world's most popular browser, and disable the built-in download manager, or at least hide it from the main menu. This does mean that it's important to remember to re-enable the built-in download manager every time you want to use the video downloadhelper, but it's certainly much easier than having to remember to go through the steps every single time.

If you really want to make the video downloadhelper companion app safe to use, you could also enable the "inconspicuous installation" of the video files, so that the files won't appear to be downloaded automatically, as they are being used. To do this, just follow the same steps mentioned above, but instead of clicking on the Download Manager icon, just click Download. By doing this, you'll then be able to play all the videos without having to worry about accidentally installing something that might damage your system.
