dear thunderbird experts,
i wish to open a new tab on a url of my choice in thunderbird 102.6.0.
my first purpose for doing this is merely to display a completely blank (and therefore non-distracting) tab when i am not using thunderbird. but i imagine i will have more uses in mind later.
thanks much for any helpful answers you can give me.
with my best wishes,
p.s. long live free/libre software!
