Rated 4 out of 5 stars

I just downloaded the extension and I was able to import all my feeds from feedly. Great! I was misiing an extension like this!
It looks that the articles attributes (read/unread - starred) are not synced, at least on my machine.
Adding this function would turn this extension in something perfect and extremely useful (also considering the total lack of a desktop rss reader that sync with feedly on windows).
By the way, does the extension work on linux and OSX too? The addons.mozilla webpage list it as a windows download but I will try it on my linux machine. Being able to use it on any platform supported by thunderbird would be great as well!
I'm available to eventually help in testing the future versions. Big thanks again to the developer!

EDIT: I've tried the extension also on linux and on osx and it works fine.
I'm looking forward to see the starred and mark as read features implemented. Then it will be really a must have extension for any feedly&thunderbird user (and I'm sure there are a lot out there). I would be glad to donate to the developer in order to support his work but I haven't found a way to contact him directly. Maybe he could add the infos for a donation directly in the notes of the next version. Keep up the good work and thanks again

This review is for a previous version of the add-on (1.1.0). 

Hello.

Starred and mark as read features are unimplemented. I'll probably keep making improvements in my spare time.

Yes. The extension works on Linux and should on MacOS, but I haven't tried, since I don't have access to such computer.

Thanks for your feedback.
