Bug ID: 481568
Summary: Plasma Integration does not work on Firefox with
AppArmor enabled
Classification: Plasma
Product: plasma-browser-integration
Version: unspecified
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Firefox
Assignee: k...@privat.broulik.de
Reporter: thepowersa...@gmail.com
Target Milestone: ---
SUMMARY
After installing Neon 5.27 and the Plasma Integration extension in Firefox
123.0 it could not connect to the native host. After some research I found that
disabling AppArmor for Firefox fixes the issue.
Article in question:
https://discuss.kde.org/t/firefox-extension-plasma-integration/4583/7
STEPS TO REPRODUCE
1. Enable AppArmor for Firefox or have it enabled on installation.
Commands to enable AppArmor:
sudo rm /etc/apparmor.d/disable/usr.bin.firefox
cat /etc/apparmor.d/usr.bin.firefox | sudo apparmor_parser
2. Plasma integration fails to connect to native host.
3. Disable AppArmor for Firefox.
Commands to disable:
sudo ln -s /etc/apparmor.d/usr.bin.firefox /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.firefox
4. Plasma Integration works after restarting Firefox.
OBSERVED RESULT
Plasma Integration does not work with AppArmor enabled.
EXPECTED RESULT
Plasma Integration should work with AppArmor enabled for Firefox like it is on
install.
