Hi,

to report problems you could also use github:
https://github.com/dennisverspuij/tb-correctidentity/issues

From your description it is not clear if this add-on could really solve your problem.

For the description I like to use two terms: "account" and "identity". (maybe check also https://support.mozilla.org/en-US/kb/using-identities).

Short (inaccurate) definitions:
account: is the email-address or username + password you use to access your mail server. (and typically has an SMTP server defined for outgoing emails)

identity: is an email address used on an account. This includes the default email address and additional mail-aliases.
An identity always uses a specific account (the one it is assigned to).

In your description e.g. in "her name <her-different-userid@gmail.com> her-name@private-domain."
the account is "her-different-userid@gmail.com" and the identity is "her-name@private-domain"

This add-on selects the "from" identity based on e.g. "to"-addresses when writing a new mail or e.g. on "to" addresses of a received mail when replying an email. (There are more functions, but maybe this is closest to your use case)

To simply select the "from" identity when starting a new mail, Thunderbird already offers a list of identites to select.
Also the default identity can be already configured without this add-on.
Even some simple rule to select this identity for replies can be configured without this add-on.
