Doesn't seem to work with reddit rss style

It works nicely, except for syncing across different machines (no refresh option on synced machines) which unfortunately for me is a big deal.

設定画面の表示が数秒で消えるときがあります。またオプションからxmlを読み込んでも、ライブブックマークが反映されません。

Бесполезно.
Не помечает просмотренные новости как просмотренные, а просто вываливает одинаковый список. Даже ранее встроенная в ФФ читалка это умела.

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!

This is an excellent replacement for the discontinued FF Livemarks. I created a folder for all my rss feeds and placed it on the toolbar. This is a simple way to keep the feeds organized and easy to scan.
My wish would be that visited links would change icon color to show already visited when reviewing feeds.

Update: Sadly the feeds do not update regularly. The only way I can force an update is to close and reopen FF.

A very good idea, but this extensions not *yet* usable (at least not in my case). It breaks the following Firefox features I use:
- Firefox sync (some RSS article links got changed to empty folders, there are problems with synchronizing subscribed RSS channels),
- Recent bookmarks "magic" folder got flooded with RSS entries (all RSS entries got there, pushing off bookmarks I added manually).
I'll update my review when things change :)
Too bad Mozilla decided to delete a good feature because "people don't use it", but they didn't actively promote it :(
