Where does Thunderbird store add-ons in Linux?

more options

I'm moving over from Windows to Ubuntu at the moment and I have a problem. In Windows, there's two folders that contain all the Thunderbird profile and add-on data. In Windows, under the user's Roaming subfolder, lives all the data that's needed to migrate the accounts and email. That simply goes in the /home/user/.thunderbird directory on a Linux machine.

However, there's another Thunderbird folder in Windows that contains the add-ons I'm using to make my Google Calendar integration work. That's located in the user's Local subfolder. But I have no idea where to copy the contents of this folder into my Ubuntu PC.

Anyone know off-hand? Thanks in advance!

all profile data on windows is stored in appdata\roaming. Anything stored in local is not forming part of the profile and is not required to transfer to another instance. The cache for instance is stored in local, it might make things faster, but it can be rebuilt.

That's what I had thought originally. However, the last time my Windows 10 box crashed, when I only restored the appdata\roaming profile folder, my aforementioned problems arose. I decided to copy the appdata\local\thunderbird folder over and everything magically appeared, so I made the assumption that it must be related.

Last night, the same thing was happening on my Ubuntu PC. The calendar and add-ons were missin. But, funny enough, after reading your post I started to wonder if it was just a co-incidence and the missing functionality would return if I gave it a few moments and reloaded, and it did. I have done nothing other than leave Thunderbird up for a minute, close it out, and reopen it. Everything has come back and I've learned something new. Thank you for your time!
