Bah n humbug! Issues with Thunderbird. Segmentation fault in the bash script. Don’t know why as this hasn’t happened before. Tried 184.108.40.206, 220.127.116.11 and revert to 18.104.22.168. May need to test with a fresh install – which I need to do anyway as the installation has installed potential dependency conflict. Oh well back to the frawing board.
