** Description changed:
Hello.
Today, Firefox has been updated to v60. After first start there was so
many problems: with new tab (errors), Sandbox option (one new option
with 'false' value). There were so many issues. No website was working,
I can not click on anything, there was no menu bar and so on. Firefox
main windows has been resized etc.
- Anyway, there was also a lot of "DENIED" entries in a log files. These
+ Anyway, there was also a lot of "DENIED" entries in a log files. Here
are the AppArmor rules, that helped and now Firefox works okay. Maybe it
will help someone too?

# profile="/usr/lib/firefox/firefox{,*[^s][^h]}" comm="firefox"capability=21
# capname="sys_admin"

#
capability sys_chroot,
# NOTE: what about an "owner" prefix?

#
dbus bind bus=session name=org.mozilla.firefox.*,
# NOTE: this rule can be found, for example, in "abstractions/X" file.
# However, there is "r" in 'requested{,denied}_mask" - for '/tmp/.X11-unix/'
# - in log entries, so I added "r" - and now it's "rw".
#
# apparmor="DENIED" operation="connect"
# profile="/usr/lib/firefox/firefox{,*[^s][^h]}"
# name="/tmp/.X11-unix/X0" comm="firefox" requested_mask="r" denied_mask="r"
# fsuid=1000 ouid=0
#
/tmp/.X11-unix/* rw,
unix (connect, receive, send)
type=stream
peer=(addr="@/tmp/.X11-unix/X[0-9]*"),
Can someone check if these rules are okay? With above rules, Firefox v60
is working okay again: web browsing, new tabs etc. There are also some
"segfaults" error in log files - together with "DENIED" rules. Here are
some of them (there is a bug report on Launchpad about "libxul"):
✗ [ 3051.788218] Gecko_IOThread[4770]: segfault at 0 ip aef1b0de sp aeb1a550
error 6 in libxul.so[aebed000+66fd000]
✗ Gecko_IOThread[4795]: segfault at 0 ip aef1b0de sp aeb1a550 error 6 in
libxul.so[aebed000+66fd000]
I hope, that above rules will help other users who will have an issues
with a new Firefox release. Here are some technical informations:
● Firefox: v60.0 (32-bit)
● Linux kernel: 4.4.0-125-generic
● Release: 16.04 LTS
Thanks, best regards.
