Firefox can't open custom `magnet://` links & `vscode://` url schemes, for qbittorrent & vscode installed in my system
- This works fine everywhere else ( chromium, konsole(ctrl+click) or plasma app launcher search.)
- firefox+debian13 gnome works fine as well.
Steps to reproduce this bug:
1. Install any application that registers "
x-scheme-handler/<protocol>" in its .desktop file.
2. try using that protocol in firefox
Current Workaround:
add "
x-scheme-handler/<protocol>" in ~/.config/mimeapps.list
I have tried this on 2025-10-20 debian-testing. It still has this bug.
