it wants to install some companion thing

Deze addon verschijnt niet in de werkbalk. Kan dus ook niet gebruikt worden. Jammer de vorige versies waren goed.

I have been a VDH user for many years. Most of that time, I have had great results. However, since the use of the VDH Companion App has become necessary, I have encountered new problems, not sure if they have been reported on the forum because most of my search questions get no results. The problem is that this VDH Companion App causes, and has done so many times now, all 4 of my iMac computer cores to come on And my fan speeds to almost max out. 1796 and higher. How do I know this VDH Companion App is causing this for sure? I used Activity Monitor to find out. Once I used Activity Monitor to shut down VDH Companion App, my core use went back to normal and my fan speed dropped to normal. I had to use Activity Monitor to Shut down the VDH Companion App because I could not figure out how to do it otherwise and it was Continuing to run, even after I had Quit Firefox. How is this even possible? No apparent way to shut it off. Another issue is that there is no easy or clear way to contact the developer that I can find. I tried, again, searching on the Firefox Support forum on the VDH page, but Nothing comes up. I can't find a way to get feedback or questions to the developer. Apparently, there is a way, because I see that people post, but I can't find it. Why is there no direct link or email feedback form posted? Most of my other FF Add-Ons have a direct way, like an email link, that I can use to contact them. I see that many people have posted issues with the VDH Companion App as well.

Toujours aussi Facile d'emploi et gain de temps.

Die neue Version verlangsamt den Computer derartig, dass man besser auf den Downloadhelper verzichtet. Schade, vorher war das ein hervorragendes Addon!

برای دانلود

Wonderful

better before new Firefox Quantum.
Now Video Downloadhelper slows down everything with 90% CPU usage :(
The external Video Downloader and Converter ffmpeg makes it unusable! :(

es un poco lento y ralwentiza el navegador
