Since Firefox 116.0 it no longer uses libnotify to display notifications through KDE. KDE 5.27.6, FreeBSD 13.2-p1 on amd64 Furthermore, when it displays its native notifications it often hangs completely so I had to turn notifications off. When it hangs the notification box becomes locked in X-Windows (e.g. previous content from another window is shown there). And all firefox windows will be unresponsive. Things checked: - About:config alerts.useSystemBackend is set to true (so it should use libnotify) - libnotify is still installed - libinotify is also installed - Don't see anything relevant to this in about:support
PS: Not sure if it affects multiple people. I have not yet been able to confirm on IRC. One person mentioned it still works on GTK based platforms so perhaps it's a KDE specific bug.
It seems working on my side, my environment is: - 13.2-RELEASE-p1 - firefox-116.0,2 - kde5-5.27.6.23.04.3_2 - libinotify-20211018 - libnotify-0.8.2
Thank you Li-Wen! It's strange, it worked totally fine until the update. I checked my versions also. They are exactly the same as yours! Are you sure you are getting the native notifications that are showing up in the panel?
Crashes should probably be a separate bug report (not reproducible here). From what I see, with multiple applications: this BR is more broadly - with, or affecting, devel/kf5-knotifications - not limited to www/firefox. <https://www.freshports.org/devel/kf5-knotifications/> At a glance, I see nothing related upstream.
Issue fixed with Plasma 5.27.7 / Firefox 117.0 Not sure what the issue was :( But glad it's fixed!
