Recently my Mozilla Thunderbird was upgraded to 5.0 on three different machines. I always prefer to use lightning to access my google calendar and keep track of my schedule. So Lightning 1.4b was installed on all machines.
But out of a sudden today Lightning stopped working on my laptop. There was not even a configuration tab anymore nor any icon in the Extensions tab. So what did I do? Restarted Thunderbird – Lightning does not work. Tried to remove Lightning – Thunderbird crashed, Lightning was not removed. So clear 6 steps brought me to the goal:
- Remove Lightning 1.4b – DO NOT AUTOMATICALLY RESTART THUNDERBIRD
- Close Thunderbird
- Open Thunderbird
- Install Lightning 1.5b
- Close Thunderbird
- Open Thunderbird again
Safe and clean method…
