Public bug reported:
After activating firefox profile, be it in complain or enforce mode, no
applet will run.
The culprit seems to be:
apparmor="DENIED" operation="open"
profile="/usr/lib/firefox/firefox{,[^s][^h]}//browser_openjdk"
name="/run/user/1000/dconf/user" pid=11973 comm=64636F6E6620776F726B6572
requested_mask="wrc" denied_mask="wrc" fsuid=1000 ouid=1000
The rules that prevent the applets to run belong to Apparmor
abstractions, specifically /etc/apparmor.d/abstractions/ubuntu-
browser.d/java
These rules will be enforced, even when usr.in.firefox is in complain
mode (I don't know why exactly)
Adding write access to the line
owner /run/user/*/icedteaplugin-*/ rw
in /etc/apparmor.d/abstractions/ubuntu-browser.d/java
seems to solve the problem.
