It doesn't work on Thunderbird 55.0b2 Noté 3 sur 5 étoiles
After applying the Thunderbird 55.0b2 update the Calendar in Montly and Multiweek view are no longer working. Disabling the Calendar Tweaks plugin all works again.
Will be fixed in time for the general release of Thunderbird 55.0 ...
This problem is caused by updates to the calendar bindings in Thunderbird 55.0b2.
This means that modifications will have to be made to the corresponding bindings in Calendar Tweaks.
This is quite a lot of work and so won't be done until a final (stable) beta version is available.
