Great Addon, have been using it for years and am very glad that it works with FF57 now.
I only have two minor complaints:
1) In some recent version the keyboard shortcut for opening Brief changed from Ctrl+Alt+D to Ctrl+Shift+D. Unfortunately the latter shortcut is already used by firefox for bookmarking all tabs. Thus Brief cannot be opened anymore using a keybaord shortcut.

2) Yesterday Brief suddenly deleted all my feeds and I had to resuscribe to all of them. Didn't happen before and I hope it won't happen again.

Anyway, great addon, thanks a lot!

Always has been the best RSS Reader and still is the best. I missed it a lot when there was the WebExtension switch (being announced so early, I wonder why so many extensions got ported that late), so I had to try out Feedbro, which seems to be more popular among users, but I don't understand why, was a big disappointment when you are used to Brief. Brief is so much easier to use, simple UI, easy to navigate with mouse and with keyboard, it's fast, it's light weight (needs little memory and CPU time), it works as expected (opening an entry opens it in a tab, marks it as read and immediately wipes it from the unread view), little preferences (which is good, I don't want to waste 2 hours on configuring a RSS reader just to make it somewhat usable). I'm so glad it's back and finally I have a quick, no sorry, a "brief" overview of all the important news again, safes me maybe a hole hour a day, as I can quickly skip all the uninteresting ones, easily read the important ones and peek at those where I'm unsure if they are interesting; that's what you use a news reader for to begin with, isn't it?

search is not working. impossible to input anything from the keyboard

Great extension, thanks ! The only one who succeeded in making me forget Sage (RIP).
I'll put 5 stars when you will add a button to push an article in pocket list ;-)
What do you think ?

liked it but migration to FF57 failed. In fact Brief doesn't work at all in FF57

update: thanks for getting back. changing the privacy setting did the trick

very reliable feed-reader. having using it for years now - before FF 57.

figuring out how to backup my feeds. no reaction when I export my feeds.

doesn't seems to start automatically when clicked ????

it runs after awhile - depend on good-luck... :-(

love it!

Works great, but how can I sync my feeds?

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

excellent addon

Thanks for porting this to WebExtensions. Best RSS Readers, I've been using it for years now.

Long time user for this extension and i'm happy that its upgraded to support FF57 ! , one issue that it seem "clear all items" button in the option not working .

lecteur permettant la prise en compte de nombreux sites avec une excellente ergonomie. Simple à mettre en oeuvre, facile à utiliser.

Hello.
Maybe this is a bug, maybe i'm only too dumb for it. ^^

If i delete feed messages how can i get it back? Delete the whole feed and re-add does not help. Uninstall/reinstall brief - does not help.
The trash is empty.

I hope you can help me (or fix this issue).

Thanks

EDIT:
Thanks for your answer. Can you please give me infos for the hard way? I also try a diff. (files), but not found where the changes are made.

EDIT2:
Its fixed. :) You only have to wait until new feeds are coming and he will load the old ones again. :)

Hello I like your add on very much but now I have a problem
I need to transfer the opml file to another computer. each time I try Brief tells me that this is not possible because of (invalid file format. the xml file isn't well formed). Please help

Thank you for your reply. Now I have another issue. when I check "oldest first" nothing happens. Is there a workaround to fix this.

It's the perfect RSS-Feedreader for me - since years! And now, with FF57, it's perfect again! Thanks for this great Addon.

edit Dec. 2018:
And now, with FF 64, it's always the best Reader!

Great Add-On but has somebody else the problem that the new version (for FF57) doesn't show the last entry first? The checkbox in the options seem to do nothing - i always see the newest entry first... regards

Update: Thanks a lot - that was my problem - i was using Brief for years and have forgotten that you have to change the view - thanks again - keep up the good work

One more suggestion - add something like "Delete all unread messages" to "All entries" - in previous version the "Mark everything as read" option has put them to the recycle bin and you could delete them there - now i have to delete all the unnecessary feeds for every entry seperatly

Made my day when I saw brief was updated
