It would be great if you could save the login details for a password protected RSS feed in Thunderbird, as currently it just asks you to re-enter you username and password every time you start up Thunderbird
One example of this issue is when I try to add an RSS feed for Pocket to Thunderbird, as it always asks me to re-enter my login details for Pocket when starting up Thunderbird.
I have included a screenshot of the window that opens every time I start Thunderbird.
