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

Any updates on the search box?
This feeds reader is the best and most flexible you could possibly find for browsers, in my opinion. It was fantastic, until the search box stopped working. The search box is the absolutely essential base part of this reader. It enabled searching through abstracts and reduce the posts only to matches. Otherwise, reading through 10000 entries per day is impossible. Almost 5 years past, but the search option still not working. I'd be willing to pay the developers to get the search box working.

Dodatek używam od bardzo dawna ale ostatnio coś się popsuło. Wersja brief 2.6.1 - Firefox: 102.0.1 64bit,
OS: Linuks 64bit. Kiedyś automatycznie otwierało nową kartę po kliku np. na ">" - teraz nie!, a ostatnio automatycznie brief kasuje czytaną wiadomość po wyświetleniu jej. Po dodaniu do zakładek, również kasuje wiadomość po wyświetleniu - raczej tak nie powinno być!.
Dlaczego tak się dzieje teraz?.

EDIT!. ff. 103.0
Oznaczenie wiadomości jako przeczytana również ją kasuje - w zakładkach także.
Dodatek pomału staje się uciążliwy w użytkowaniu - jak rozwiązać te problemy?

Have used this for years and still my favourite, but as mentioned before I cannot re-order my feeds anymore. Can anyone help?

Impossible de déplacer ( glissé-déposé ) un flux pour le mettre dans un dossier .

По сравнению с другими лучше. Но Поиск - просто элемент дизайна.

Great addon! I really enjoy it.

But one thing I wish to be fixed. Brief doesn't work when I move my firefox profile from default folder to other drive .

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.

默认ui美化差点，但是总体体验太好了，简直完美

SQLite database of this add-on has became 500MB after several years of usage. Deleting of old items does not help to shrink database :(

J'adorerais mettre les 5 étoiles, le détail qui m'embête c'est que les notifications n'affiche pas les titres d'articles, uniquement le nombre. J'aimerais en cliquant sur la notification, être redirigé vers l'article sur le site web. Ça serai moins contraignant et ça rendrais Brief vraiment indispensable. Merci pour votre travail.

Very nice, thanks for that!
User luprobert created a Dark Mode, works nice, have a look: https://github.com/luprobert/briefnightmode

This is great, thank you so much! It would be very nice to have keyboard shortcuts to change between the feeds.

Best feed reader there is.
For me, the only missing feature is an ability to edit the feed's URL.
