Have you installed the latest version of the Plasma Integration Firefox Addon? I can see this Addon was last updated more than a year ago and Firefox may have changed since then. > I tried to install the package "kde-plasma/plasma-browser-integration" > and restarted my computer, and the problem still exists. Switching to > Wayland doesn't help too. The package 'kde-plasma/plasma-browser-integration' is usually installed by 'kde-plasma/plasma-meta' with USE="browser-integration" enabled. It seems Firefox, or more likely the Addon is not finding this file. > I use Arch on the same computer before, but > the problem doesn't exist when I using it. Do you have the Arch installation to check the path(s) where the file org.kde.plasma.browser_integration.json is installed? This is what I have on a Gentoo plasma installation here: ~ $ locate org.kde.plasma.browser_integration.json /etc/chromium/native-messaging-hosts/org.kde.plasma.browser_integration.json /etc/opt/chrome/native-messaging-hosts/org.kde.plasma.browser_integration.json /etc/opt/edge/native-messaging-hosts/org.kde.plasma.browser_integration.json ~/.var/app/org.mozilla.firefox/.mozilla/native-messaging-hosts/ org.kde.plasma.browser_integration.json /usr/lib64/mozilla/native-messaging-hosts/ org.kde.plasma.browser_integration.json Perhaps you can check what file the Firefox Addon is trying to access, by running 'about:debugging' and connecting locally to it: https://firefox-source-docs.mozilla.org/devtools-user/about_colon_debugging/ index.html > Thanks for reading.
