Package: firejail-profiles Version: 0.9.62-4~bpo10+1 Severity: normal When using Thunderbird under firejail, the ability to open links (e.g. clicking them) is largely broken. If Firefox is the default browser, then it opens a new Firefox profile as it was opening for the first time. It ignores the existing Firefox setup. If xdg-open is the default browser, then it does nothing. I added "ignore nodbus" to thunderbird.local, that does not seem to change the link clicking.
To test this, I ran: firejail --profile=thunderbird firefox https://f-droid.org firejail --profile=thunderbird xdg-open https://f-droid.org I also tried lots of other profiles to see with which xdg-open worked. If found xdg-open worked with awesome, blackbox, and caja then I stopped trying other profiles. So this works: firejail --profile=caja xdg-open https://f-droid.org But then this does not: firejail --profile=caja --apparmor xdg-open https://f-droid.org Adding "ignore apparmor" to thunderbird.local did not seem to fix the link clicking though. Maybe the thunderbird.profile has multiple issues preventing link clicking. Since it includes the firefox common profile, link clickability was not a factor in the Firefox setup, since clicking links in Firefox always opens them in Firefox. -- System Information: Debian Release: 10.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (100, 'proposed-updates') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-9-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages firejail-profiles depends on: ii firejail 0.9.62-4~bpo10+1 firejail-profiles recommends no packages. firejail-profiles suggests no packages. -- Configuration Files: /etc/firejail/meld.profile changed [not included] -- no debconf information
