How to subscribe to private RSS feed that requires authorization?
In previous Thunderbird versions, when you subscribed to a RSS-Feed that required authorization, Thunderbird prompted for it, just as a Webbrowser would.
I'd enter the username and password, tick the box "Save in Password manager" (or something) and the feed would come in.
I don't know when that changed, but nowadays Thunderbird just says "Feed is unautorized". No password prompt, no possibility to mark a feed as "requires Authentication".
I know I could pass username and password in the URL, but that is rather unsafe compared to saving the password in password manager protected with a primary password.
It seems that there were some bug reports some 21 years ago about the same issue, so maybe this is a regression?
