can't add RSS subscription; says it already exists
Greetings.
After updating to 128.2.0esr (64-bit), my RSS feed for DimeADozen (http://bt.dimeadozen.org/rss/) stopped working. It requires a username+password. I removed the subscription and deleted the subfolder from Blogs & Newsfeeds, but when I tried to add it back, the URL returned "The Feed URL is not authorized." I checked the version of Thunderbird, and apparently the update hadn't fully applied, as I was told to relaunch. After doing so, when I try to add the feed, I get the message "You already have a subscription for this feed." It is not listed in the Feed Subscriptions window.
Please help.

I did a bit of poking around in Windows AppData, specifically in the Feeds folder, and managed to edit feeds.json to remove the entry for Dime-A-Dozen, without corrupting the two working feeds. Now instead of the messages listed above, I see "The Feed URL is not authorized." Given this feed was working prior to updating to 128.2.0esr (64-bit), what changed in Thunderbird to break it? Is it not authorized because it requires a username+password? If so, why did that work before updating Thunderbird?
Note that before editing feeds.json, when I was getting "You already have a subscription for this feed.", only the other two feeds were listed, just like in the attached screenshot. So, subscribed but invisible.
