Review for Quicktext by Shamitss
Rated 5 out of 5 stars
Agreed that this is an incredibly useful addon once you are used to it.
Unfortunately not working with Version 72 beta1 released Dec 4th 2019.
I tried the unistall and re-install but Thunderbird won't even let me re-install as it is no longer compatible. This was probably my most useful addon.
