I think there is no Orthodox translation in French.
You can try the last edition of La Traduction œcuménique de la Bible (the Ecumenical translation of the Bible) or TOB from 2010. It contains the deuterocanonicals of the Roman Catholic Church, as well as the extra books accepted by the Orthodox churches only - 3 and 4 Esdras, 3 and 4 Maccabees, the Prayer of Manasseh and Psalm 151. Their addition involved St. Sergius Orthodox Institute in Paris. Probably it's the first French bible which contains them. You shoud notice that earlier editions (from 1975, 1988, 2004) don't include these books, but only the Roman Catholic deuterocanonicals.http://www.editionsducerf.fr/html/index/collection.asp?n_col_cerf=102&id_theme=1&id_cat=254http://www.la-bible.net/page.php?ref=TOB/2010
- you can preview extracts from 3 Esdras and the Prayer of Manasseh.
Another version is la Bible de Jérusalem or the Jerusalem Bible, which includes the deuterocanonicals accepted by the Roman Catholic Church. It has three editions - in 1955, 1973 and 1998.http://www.editionsducerf.fr/html/fiche/selection.asp?id_selection=65&id_theme=1&id_cat=253
Both translations are avaliable online. It's the 2004 TOB edition, so it does not include the extra books of the Orthodox. La Bible de Jérusalem is in its third edition from 1998.http://bibliotheque.editionsducerf.fr/par page/120/TM.htmhttp://bibliotheque.editionsducerf.fr/par page/84/TM.htm
