Hi On Wed Jan 11, I've sent the first message to this list describing a problem with Firefox and plugin-container crash etc. Adding one rule to the Firefox profile were considered as a solution to the problem. It was something like this one:
owner @{PROC}/[0-9]*/task/* r, But; on Jan 24., Firefox has closed again - without any reaction from my side - and system log files, such as '/var/log/kern.log' or even '/var/log/syslog' logged such entry (this time without AppArmor DENIED message [1]): Jan 24 19:36:15 t4 kernel: [18353.035413] Chrome_ChildThr[2753]: segfault at 0 ip b76e3673 sp b1efe9f0 error 6 in plugin-container[b76dc000+42000] In the meantime, I've added one more rule to the Firefox profile, which, as we can see, helped. Now, AppArmor rules related to this issue looks this way: owner @{PROC}/[0-9]*/task/ r, owner @{PROC}/[0-9]*/task/* r, Seth, You've asked about creating a bug report: "Please file the bug report against the firefox source package (...)" So, here it is: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1656065 I hope, that it's a "good" report. If there is something, which I should add/remove please let me know. It seems, that I definitely should edit this report and add an informations about second AppArmor rule etc. Best regards. ____________ [1] first AppArmor entry: https://lists.ubuntu.com/archives/apparmor/2017-January/010441.html
