This add-on is not necessary anymore because with Thunderbird 115 you can easily move/sort your folders.

Edit:
Reordering the folders or accounts
from
example_C@example.com
example_A@example.com
example_B@example.com
to
example_A@example.com
example_B@example.com
example_C@example.com

Do you mean accounts rather than folders? Then it's possible from Thunderbird 91.
Unfortunately, 115 still cannot move/sort folders.

Edit:
Okay. You mean about accounts, not folders.
