Not working at this moment.

簡單好用。
Very useful.

(English below)
Presque parfait, fonctionne à peu près comme l'ancien lecteur de flux de Firefox. Seul reproche : les icônes ne sont pas personnalisables.

Almost perfect, works roughly as the previously existing Firefox RSS reader. Little nitpick: I would like to be able to have the website icon as the folder image (but does Firefox allows that?) and have the icons change instead of an added checkmark (which is not as visible as the yellow RSS icon turning gray)

This is just what I was looking for - thank you! :)

I would love to try this, but I am not psychic. WHERE are the directions? How do I use it to clean my bookmarks of dead links?

I am sitting here stunned right now. I have been holding onto a v.56 fork of FF for years now solely because of Liveclick, the legendary livemarks enhancement addon that was sadly abandoned when it seemed RSS folder functionality had been made impossible in "Chromefox". And now here I am looking at the impossible on my bookmarks bar. I would swear I've read the name Tim Nguyen associated with addons in the past, too. In any case I can't express my appreciation for this breakthrough enough and I can only hope that Mozilla doesn't somehow wreck this feature YET AGAIN. Obviously what I and many other newsfeed junkies would love to see next is as much of Liveclick's power as possible added to this new extension. Being able to have the titles of unread articles shown in boldface was a godsend, with a configurable timer that would mark them as read after a certain number of seconds! I'm guessing its probably either very difficult or not even within reach, however, considering the lack of flexibility in anything with Chromium DNA. Ah, the days when it was all about empowering the user...how I want to see those times return :)

Suggestions that hopefully might be possible to implement without too much trouble:
* Option to keep FF from shortening titles of articles. I know FF has always had a stupid arbitrary limit to the length of titles on the bookmarks toolbar but I can't find a solution like Place's Full Titles any longer.
* Either a way to support the syncing of Livemarks to our FF account bookmarks or an export/import function just for Livemarks.

This extension was great, but after the update to Firefox 79.0 (windows 64 bit) it no more works :-(

----------------------
(update: SOLVED :-) it was the use of CCleaner that cancels some sqlite archives in Firefox. Thanks to the developers of this extension)

At last a MUST HAVE for feeds ! Would it be also possible to add an option to mark ALL feeds as READ without opeing ithem. Thank you for this absolute great work.

Should be able to synchronize the bookmark list with Mozilla Firefox Sync (or/and other cloud services) to avoid/automate export-import work.

Kein Icon rechts oben, daher nicht zu gebrauchen.
Falles es über die Einstellungen eines gibt, ist es schlecht beschrieben!

very helpful addon save lot of time

Livemarks eklentisi harika, Eskisi gibi Rss beslemelerini almak çok güzel...
