As of 16 June PureOS update, Thunderbird no longer opens web links in Firefox (default browser). I executed:
to verify that Tbird opens links in Firefox when apparmor is OFF.
I have fixed this in the past with a change to apparmor config but I can’t find any document I saved to document this fix and I can’t get past all the extraneous help answers to find one that documents the apparmor config change necessary to re-enable Tbird links.
I would appreciate a link or edit to fix this problem.
