Hi I am running Kubuntu 20.04 LTS
I always use thunderbird for years now.
However from the software store it seems to install the snap.
Everytime it updates It loses my contact list and i have to re-enter my email address.
Even though i have it set to not update.
I wat to get rid of it unless theres a solution I don’t like the way this snap works.
I too use Thunderbird. I really needed the cardbook extension, and Calendar, as these both integrate well with Nextcloud (via CARDDAV and CALDAV).
I simply download the .tar.bz2 file right off the Thunderbird website. No package manager here (against all of our better judgements, admittedly)!
Once I decompress this, and move the “thunderbird” folder to my home dir, then I make a symlink to the actual thunderbird executable binary on my desktop:
