Ubuntu24 apparmor profile required
With linux-kernel 6.8 (like on ubuntu 24) apparmor profiles becomes required. Otherwise all tabs of librewolf will immediately crash, logs will refer to SEGFAULT with signal 11.
From the firefox apparmor profile reference i got here
# This profile allows everything and only exists to give the
# application a name instead of having the label "unconfined"
abi <abi/4.0>,
include <tunables/global>
profile librewolf /usr/share/librewolf/librewolf flags=(unconfined) {
userns,
# Site-specific additions and overrides. See local/README for details.
include if exists <local/librewolf>
}
This is tested and restores normal functionality.
With a little directions i can make this a PR.
