You can check Feedbro as an alternative to Brief: https://addons.mozilla.org/en-US/firefox/addon/feedbroreader https://addons.mozilla.org/en-US/firefox/addon/feedbroreader I was a long time user of Brief but moved away during the transition to webextensions. Although Brief worked there were some performance issues at the time (maybe solved now?). Both provide a similar user experience, and are the two best RSS readers I used so far.
