Hi,
I tried to install Varia in Flatpak on my Linux Mint Cinnamon 22 and I had no problems doing so. I also installed the plugin for Firefox.
However:
1- when I try to download a video from Youtube, it downloads an html file.
2- if I click on Video/Audio I get ‘No video or audio found’.
3- I don't understand how the plugin should work: if I go to a video page on YouTube, it doesn't automatically send it to Varia; if I click on the plugin it simply shows me this image

How do I make it work? Isn't there a Wiki page or an FAQ?

Thank you very much and best regards.
