Thunderbird nebula 128.2.3esr (win10)
Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.
