Hi,

After more than 2 years with this issue, changing things in numerous files, Advances Settings and so on, I finally solved it today.

For those who have this issue, who can't open links, with Thunderbird asking you what application it has to use, but no suggestions, all you have to do is to install:

• xdg-desktop-portal

And, according to you environment:

• xdg-desktop-portal-gnome (Gnome)
• xdg-desktop-portal-kde (KDE)
• xdg-desktop-portal-xapp (Mate, XFCE…)

You get the idea.

It's weird that those packages are not installed by default, let me now if this solves your issues too, so everybody can finally enjoy using Thunderbird again!

Best regards,
