I need to install a newer version of Thunderbird due to data compatibility issues. The current version (68.10) installed via apt is less recent than that I need to install - and the snap versions available are much more recent still - around 78.5 ...
I know how to crudely install Thunderbird: just download, unzip to some file location and then double click on the /thunderbird/thunderbird executable file.
The problem after this process is that:
- Thunderbird will not show on the Show Applications menu at all
- Unless downloaded to a folder in a given user account's files, the Thunderbird executable cannot be started due to permission issues.
Naturally, I would like to have this application available to all users on this PC, not just admin. And I would like a "normal" launcher icon for the Show Applications tray.
