Noté 1 sur 5 étoiles

It never showed the claimed button in the main toolbar even after relaunching and enabling/disabling the addon.

Version 1.7
Thunderbird 91.9.1
Linux Mint 20.3 cinamon

Cette critique concerne une version précédente du module (1.7). 

TB team (as of March 30th, 2023):
The missing button is a customization issue and might be related to a bug which was fixed last year. The button can be manually returned in those case, by opening the customization.
