Firefox dropped rss-support... I very often use rss feeds from several sites to stay up-to-date, so I was very disappointed about this. Luckily I found an article where someone pointed to this plug-in. Problem solved. Happy me :)
Thanks to the developers.

Most (severe) performance and stability issues of previous versions seem to be solved. It still seems to needlessly update all feeds after a restart (and possibly bad and too many feeds could still lead to issues, but I culled my feeds to a minimum so am unaware of such persisting issues).

Also the feeds flood the "recently bookmarked" list with entries that shouldn't be there (I only want to see **my bookmarks** there, not random news articles).

Thank you! Great to have the RSS folders back on my bookmark toolbar for quick and easy reading.

Does not behave the same across Mac and Linux platforms. Cannot use in present state. Has promise.

Necessary just to slow down the rate FF is going to dump (self-censored because writing the blunt truth is against guidelines apparently).

Super! I was quite frightened when Ffx updated to v64 and reported the end of livemarks. Then I discovered this extension and I really like it. As the others already said: I also would appreciate read/unread flag and custom icons - then it would be a perfect 5 for me. Thanks anyway!

Live RSS were basically the reason I stick with Firefox ... Livemarks saves this, but with 2 (quite big) limits:
1. Your bookmark has an anonymous folder icon instead of the real website icon.
2. No way to track which feed you have already read or not.

Great replacement for the removed livemarks feature.
Only two missing things:
- custom icon for the feed title (instead of folder, a RSS one would be better)
- longer feed items titles length
I'm not sure if those two things are possible though.
I also have a bug: livemarks options pop-under (in Livemarks options) have a 5 seconds delay before getting displayed

Good replacement but please add read/unread indicator (as it was before in firefox). Thanks

Working simillar to the discotinued Firefox Rss for me.

Too bad the functionality was removed from Firefox. This plugin seems to be a good replacement. The only thing I miss so far is a read/unread indicator for each news.

Presentation is nowhere as compact or easy to quickly scan as the original Firefox RSS and consequently I probably will not use this add on. I do not understand why the author didn't compact the display of live feeds so that users can see all that is available without having to scroll and scroll and scroll!

The only one that works exactly like the old live bookmarks.

What responsiveness of the developer!
The read / unread indicator is now available , less than 10 days after being requested, and, therefore, I give this extension 5 stars!

Like other reviewers, I would add star(s) to this extension if some read/unread indicator was available (as it was the case in reader integrated into FFx before rev 64)

it works if you have 8,9 feeds but when I try to load my 90 feeds , firefox freezes and cpu consumption goes to 100%. I think the best solution would be to simply load the feeds when they're selected (lazy loading) not all at once trashing the whole computer . Unfortunately for now is not usable and I disabled the addon, looking forward for the next release though

This works good. Like others are saying though there needs to be a way to indicate if something has been read or not like the old firefox live bookmarks.

Edit: I just noticed the subscribe icon in the url bar. I've gotten used to not seeing what i've read already. This add on is amazing.

Please add the function to sync live bookmarks between computers and indications for read pages. I would give this add on a five star rating if so. Thanks.

-edit: updated review to 5-stars as promised since the requested features have been delivered. It's amazing how reliable the syncing works.
