My apologies if I’m saying something stupid, but I see that this is built on top of Drone, which stopped being Open Source several years ago. Does this means that Drone, as part of Gitness, has become Open Source again?
New Pipe unofficial fork with Sponsor Block if you want to skip ads
I’m using Librewolf (a Firefox fork) and have the same issue.
Just check Firefox messaging folder exists in your home
ls -l ~/.mozilla/native-messaging-hosts
In my case, I needed to create a symlink to make it work with my browser
ln -s ~/.mozilla/native-messaging-hosts ~/.librewolf/native-messaging-hosts
Maybe you could apply a similar workaround. Hope this helps
