I don't understand addon's functionality from it's description

Seems to be broken. Cannot subscribe to feeds at all, as the mechanism for subscribing seems to be absent. I cannot set Brief as my default RSS reader. Sorry, brief, this one needs some work before it can become useful.

would be nice if any of the instructions for adding a feed were current. Hard to use when you can't any content -go ahead try to add the bbc feeds using your instructions. already moving on to some thing else.

Ten dodatek to jakaś lipa! :-( Nie można pododawać ręcznie żadnych źródeł aby to rozszerzenie powiadamiało użytkownika o nowych wiadomościach z danej witryny internetowej :-( nie może nawet użytkownik wielu innych adresów stron internetowych pododawać do tego rozszerzenia i tak go zaprogramować w jakiej kolejności ma o czym poinformować i w jaki sposób ma ten dodatek powiadamiać danego użytkownika o czymkolwiek :-(

Problems with updating my feeds. Havent updated them for 5 days now.

Перестал обновлять ленты.

При попытке добавить ленту получаю :

Файл не найден

Firefox не может найти файл chrome://brief/content/brief.xhtml?subscribe=https://mysku.ru/rss/.

Проверьте правильность введённого имени файла, соответствие регистра и отсутствие других ошибок в имени файла.
Проверьте, не был ли файл переименован, удалён или перемещён.

Есть решение?
Спасибо

lässt sich seit dem letzten FF update 61.0 64 bit gar nicht mehr aktualisieren....insofern sinnfrei...
bin zu opera gewechselt !

After the update to 2.5.8 Brief worked during one single day.
I have deleted bookmarks from the folder but they still appear in Brief menu. No idea of where is Brief taking them from.
Really a pity for such an excellent add-on. Any solution?

Unfortunately the feeds have all disappeared yet in 2.5.7.
I wait bug fix ;)

Версия 2.5.6 Выпущено Май 27, 2018 311.7 KiB - фуфло!
Откатил на Версию 2.5.5 и все снова заработало.

Хорошая попытка , но я уже привык, пока вы раскачивались, к Feedbro. Более всего огорчает открытие текущей новости в неактивной вкладке! Ну бесит же !!! Поддержка видео не работает... Тем не менее остаюсь горячим поклонником BRIEF, и желаю разработчикам успехов!!! ЖДУ..................................

Looks like the nicest RSS Reader in existance BUT: Not working in Firefox Developer Edition Version 60.0b4 46-bit

Can't see any contents on the big right side area (it states "no items") and on the left hand menu there are items that I can open up (under the feed name), but they do not have any title/text. So I do recognize that there are items as I have the arrows I can click at that show that they contain content, but there's just no text there.

I tried adding:

A bunch of my feeds aren't updating. The feeds themselves are working. I thought I would try to remove the addon and reinstall it, but it retains whatever messed up data that is causing the problem. Is it just me who's having this problem, or has nobody noticed? If it were just one or even two feeds I wouldn't have noticed for maybe weeks. But I have at least five out of 30 feeds that are broken. No apparent way to "reset" the addon.

Not working any more on FF 60.0.1 . You can't add new feeds to Brief.
