First, thank you so much for creating this. Mozilla's decision to remove the native reader was unexpected.
I like this add-on because it is simple and does exactly one thing and does it well.
It took a little work, but I have imported the live bookmarks that Firefox auto-exported on the update to 64. I had problems with dupes but that seems to have died down. I used another add-on (Bookmark Dupes) to clean up the list and it seems stable now that it has finished the initial import.
Editing my review a couple of years later just to say this is still one of my favorite Firefox extensions. I have no idea why Mozilla took out the native support, but this is exactly what I need.
When researching the latest news, the ability to open every single story with "Open All in Tabs" is a time saver as well.

Thank you for providing a replacement for Live Bookmarks (which is removed in Firefox 64)!

Saved the day. Thanks for a great product.
* Is there a way to customise or show site icons or favicons, with the Livemark bookmarks.
* A manual or set of instructions would be useful.

is there a way to automatically or semi-automatically change my existing folder structure with live bookmarks into an importable OPML file with livemarks?

Must have! Simple, works fine, import/export your feeds. Missing a reload now button somewhere.

Works well and looks nice. Although I don't think it can read from files which may be a problem.

This replaces live bookmarks really good. I love to glide through the bookmarks without being distracted and installing a separate rss feeders or using extensions wich need extra windows is too much for me. thank you!

It does what it promises ! Thank you !

This is the real substitute for the live feed killed in firefox 64, at the moment there is only a problem on some double entries

Guter Ersatz für die LiveMarks, läuft problemlos. Funktioniert. Meine Empfehlung dafür...

Good follow-up for the old live bookmarks. Didn't encounter any problems yet. I'd like to at least be able to choose between some icons though, the icon could use some color imho. Anyway, keep up the good work!

Good replacement addon for the abbandond live bookmarks in future firefox releases.
Some minor things are to be done yet, but its promissing !
Try it, or you will regret it :)

This addon is important because Mozilla has abandoned free and open web technologies.
They've deprecated Livemark RSS/Atom feed reading to be removed by Firefox 63. They are now going to be pushing Pocket, which is a proprietary technology that they purchased, with the belief that focusing all their efforts on that will get them beyond 5% overall browser marketshare.

As of August 2018, I've found this addon has stopped updating[0] for me. Similar behavior to how I found Foxish in Chrome to function years ago. I'll update my review as things change, but I'm close to abandoning Firefox altogether after 16 years of using it, since it was Phoenix. The only thing left are containers and the dedicated search bar.

UPDATE 10/17/18- all problems resolved. This is now better than Foxish ever was. Changed rating to 5 stars.

German special charakters like äöüß can not be displayed yet.
For example this feed: https://rss.golem.de/rss.php

Also a site visited marker would be an awesome feature.
