Word of Life and Passa Parola firefox extension

A firefox extension with the following caracteristics:

A one line page below the bookmarks bar to show two sentences: one is the monthly sentence of the Word of Life (https://www.focolare.org/en/mariapoli/archivio-parola-di-vita/) and the daily Passa Parola sentence (http://passaparola.focolare.org/). The extension must fetch and update the sentences automatically and it must have the option to choose the languages of the sentences (the ones that are available from those two sites).
