Feedly Enhancement Suite

I'm looking for a Firefox for Androis add-on that lets me add easily a webpage/article opened in Firefox to my Feedly "read later" board (or any other board i currently have). I have such an add-on on Firefox desktop (Feedly Mini) but can't find anything similar in Firefox for Android add-on store. The only other extension I found, relating to Feedly, discover RSS feeds on a page and adds them to Feedly, but can not add a single article to a board. According to this extensions description, I expect (wrongly ?) this extension to be able to do this - although I'm not sure what a "Leo board" is, in the description, and if the process "Feedly feed to board" matches my search. Unfortunately, I don't understand how it works, or if it can do this. Even though I claims to use the current Feedly session, feeds and boards drop-down menus are not populated (empty). And the "refresh Feedly data" button does not work. When clicking it, the button text fills with its own HTML code doe, and HTML entities if we click again on it. The extension not seem to present any other way to login to my feedly account. Not sure this extension can do what I want. I give 2 stars only for the promise. Will give 5 if I can make it work according to my expressed needs. I am on a Samsung Galaxy S9+ with Android 10. Thanks in advance for getting back.
