Rated 5 out of 5 stars
After re-installing Brief 1.5.1, I read the "splash" page about it. It seems that "Live Bookmarks" is no longer Brief's default feed location. Now it's "Subscribed Feeds". After I moved everything to this folder, all is now right with Brief!This review is for a previous version of the add-on (18.104.22.168-signed).
