Bah n humbug! Issues with Thunderbird. Segmentation fault in the bash script. Don’t know why as this hasn’t happened before. Tried 22.214.171.124, 126.96.36.199 and revert to 188.8.131.52. 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.
