Remembering the Forum's admonishment against downloading S/W other than with
Synaptic Package Manager or sudo apt-get install, I'm faced with this
dilemma: The only place I can find the add-on for removing duplicate messages
from my saved emails is here:
https://addons.mozilla.org/en-US/thunderbird/addon/remove-duplicate-messages/?src=ss
or here:
https://addons.mozilla.org/en-US/thunderbird/addon/remove-duplicate-messages-alte/?src=ss
How do I manage this through Synaptic Package Manager or sudo apt-get install
?
Doing a search in Synaptic Package Manager returns a long, irrelevant list of
scripts.
I hesitate to add this mozilla.org URL to my list of sources unless there is
an "official" means of doing so.
