Thank you in advance :)
Look for native messaging. It needs a flatpak portal or some weird workarounds.
Other addons like kde connect, keepassxc-browser, zotero, umd and others are also affected
Ah I see, thanks for your help :D
The way I have it, is that I copied org.kde.plasma.browser_integration.json from /usr/lib/mozilla/native-messaging-hosts/org.kde.plasma.browser_integration.json (for Kubuntu 22.04, might be elsewhere for you) to ~/.var/app/org.mozilla.firefox/.mozilla/native-messaging-hosts and then changed the
path
to a shell script that calls the original executable withflatpak-spawn --host
. Of course this kind of breaks sandboxing since you are allowing the browser to access programs on your machine but it works.So I have: org.kde.plasma.browser_integration.json :
{ "name": "org.kde.plasma.browser_integration", "description": "Native connector for KDE Plasma", "path": "/home/username/.var/app/org.mozilla.firefox/.mozilla/native-messaging-hosts/org.kde.plasma.browser_integration.sh", "type": "stdio", "allowed_extensions": ["plasma-browser-integration@kde.org"] }
and org.kde.plasma.browser_integration.sh
#!/bin/bash flatpak-spawn --host /usr/bin/plasma-browser-integration-host "$@"
Don’t forget to
chmod +x
the shell script.I have the same for the KeePassXC extension.
