Comment 2 tobias.teichmann 2024-06-25 06:53:47 UTC 
I have the same issue on Arch Linux as bugs.kde.org@whysthatso.net.
But I noticed, that the crash does not happen, when I run '/usr/bin/plasma-browser-integration-host /usr/lib/mozilla/native-messaging-host' manually in the console. When run manually the host behaves as expected and provides the browser integration.

Here my crash report:
Application: plasma-browser-integration-host (plasma-browser-integration-host), signal: Aborted
