Thunderbird, I can go to Add-ons manager, search for extension, and click on
Add to Thunderbird to install it.
But I have multiple Thunderbird profiles, and installing every extension in every profile is tedious.
Is there a way to download the extension file, unpack it somewhere (presumably in /usr) so that all clients, all users, all profiles can see it as available and use it?
I foundsimilar question here but that does not seem to work any longer in newer versions of Thunderbird. The paths are definitely different.
I am using
As an example, here is an extension that I would liketo install globally: No Message Pane Sort
I have tried installing that extension from Add-ons manager, and it works. So it is definitely compatible with my version of Thunderbird.
However, when I tried to unpack the file in
/usr/share/xul-ext/nomessagepanesort/, other clients (other thunderbird profiles) don't see it.
