Excellent add-on, highly configurable, really helpful, clever, time saver. It can be better on font readability, short preview readability, options placement and other small things that can make Feedbro easier to use for non pro users. Maybe an android version option to save everything you like in a personal feed (even publishable) should be great. Maybe even an android stand alone version to have all of out feeds, given the fact you can't install it of firefox for android.
Thx for the effort and for the community.
