If you downgraded Thunderbird from 78.2.1 to 68.12.0, as this is not supported upstream, I am not that surprised. On the other hand I upgraded Thunderbird to 68.12.0 from 68.11.0 in Slint (both genuine Slackware packages intended for Slackware 14.2) with no issue.

Would be possible to have also mozjs-78 ?

A stable XFCE 4.16 is imminent - maybe at this point 4.14 should be skipped; since --Current is still at 4.12.

For a while I have wondered if part of the 15.0 holding pattern might be related to waiting for 4.16. Just speculating of course. :D
