Adding bulk mailaccounts via import-addon or csv file


i hope my english will be good enough to properly explain my problem and what i am looking for:

I need to add a lot of different mailaccounts to Thunderbird. Mailaccounts from &

if i add each one seperately it would take ages with boring copy & paste work. That’s why i was looking for any bulk upload/import solution which i can feed with a textfile containing the accountsdata each on one line, like:; mailaddress;password

I wasnt able to find a solution for that.
Can someone maybe point me in a direction to solve my problem.

Thank you very much
