BRIEF 2.5.8
It does not update feeds anymore, not even manually.
This has happened since yesterday, since firefox has updated to version 60.0.2
tips?

UPDATE
BRIEF DON'T WORK WITH FIREFOX 60.0.2
I'M RETROCESSED TO BRIEF 2.5.6, AND THIS WORKS PERFECTLY

Feed Update problem solved: In my case "CCleaner programme" which I run daily erases "permissions.sqlite" file. Once I add this file to the exclude list, everything works fine.

After getting feeds working now Brief continues to reload the same feeds over and over even with the hide read feeds enabled. There's no recognition that any previous feed has already been downloaded and viewed ???? I end up with constant multiple instances of the same feed.

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.

2.5.6 and 2.5.7 still can't find my feeds. Thankfully 2.5.5 still works. Will be worth 5 stars once fixed.

Love Brief. Have used it for years, but after the latest update on 5/27/2018 it has stopped working. The feeds have all disappeared.

Mobil platform da kullanılabilmesini sevdim.

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:

Wow, finally an rss addon that suits me!!! Almost the same as Sage and Sage++ !!!
Here're some suggestions:
Please, can you please put like Sage(++) did, on the left pane, divide that space in two and at half below put a list of all feed articles titles from the feed that we are reading?! It would be much better than we scroll all the articles in the right pane!!
One more thing, can you please add firefox sync to the addon options and feeds?!
Thkx in advance.

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.

Era una de las mejores extensiones que he usado, sin embargo desde la actualización de mozilla a quantum es imposible usar la barra de búsqueda de Brief para encontrar detalles en cualquier noticia, por favor mucho sabría agradecerles soluciones este problema para que siga siendo N° 1 en aplicaciones realmente útiles...

Very good extension
but the fact of not being able to synchronize between these pc is penalizing
I hope this feature will be implemented someday
