(English below)
Presque parfait, fonctionne à peu près comme l'ancien lecteur de flux de Firefox. Seul reproche : les icônes ne sont pas personnalisables.

Almost perfect, works roughly as the previously existing Firefox RSS reader. Little nitpick: I would like to be able to have the website icon as the folder image (but does Firefox allows that?) and have the icons change instead of an added checkmark (which is not as visible as the yellow RSS icon turning gray)
