I'm not an Ethiopian, but since they were mentioned here and they are the daughter Church of the Coptic Orthodox Church of Alexandria of which I am a member, I feel confident in presenting this from an
Ethiopian Orthodox Tewahedo website, which explains their unique canon to some degree:
The Holy Scriptures are one of the two great foundations of the faith and here is what our church holds and teaches concerning it. The word of God is not contained in the Bible alone, it is to be found in tradition as well. The Sacred Scriptures are the written word of God who is the author of the Old and New Testaments containing nothing but perfect truth in faith and morals. But God’s word is not contained only in them, there is an unwritten word of God also, which we call apostolic tradition. We receive the one and other with equal veneration.
The canon of the Ethiopic Bible differs both in the Old and New Testament from that of any other churches.
List all books. As a whole, books written in the Geez language and on parchment are numerous. The Ethiopian Orthodox Church has 46 books of the Old Testament and 35 books of the New Testament that will bring the total of canonized books of the Bible to 81.

The Ethiopic version of the Old and New Testament was made from the Septuagint. It includes the book of Enoch, Baruch, and the third and fourth Esdras. In the international Bible studies there are certain books belonging to the class usually designated pseudepigraphic. The whole Christendom and whole-learned world owes a debt of gratitude to the church of Ethiopia for the preservation of those documents.
Among these books is the book of Enoch which throws so much light on Jewish thought on various points during the centuries immediately preceding the Christian era. The book of Jubilee (Kufale, i.e. Division) otherwise known as the Little Genesis has also been preserved entire only in the Ethiopic version. The preservation of yet one more book in its entity, namely, the Ascension of Isaiah, is to be remembered to the credit of the Ethiopic Church.
It should be noted that the Axumite Church (modern day Ethiopia and Eritrea) received the scriptures in a
pre-canonized state (that is to say, pre-39th festal letter of HH St. Athanasius the Apostolic, 367 AD), just as all the ancient churches did. So the concept of what the canon even
is is a bit different, I suspect, because they had local books (i.e., Ethiopic translations of works that have otherwise been lost, as the website says) that made it in precisely because of their value to the Ethiopian Orthodox Tewahedo Church
in particular (nobody else was reading Ge'ez, the language of the court and the Church at the time). And the Coptic Orthodox Church, which is the first Church of Africa and the mother of the Tewahedo Orthodox churches in East Africa (dating back to the time of HH St. Athanasius the Apostolic, who sent the first bishops to Axum after the death of St. Frumentius, the Syro-Greek Phoenician who converted King 'Ezana), has obviously never cared to institute some kind of inorganic uniformity upon the Ethiopians and Eritreans.
And since Protestantism happened in the West, not the 'Orient' (ugh), there was technically never a closing of the canon among any Oriental Orthodox that I am aware of. This is simply not an issue, just as there is no division into this or that (though there are plenty of books that are not in the canon that are still beneficial to read which may be divided this or that way, as per the website's lists). I don't know about Ethiopians, but I suspect the Copts only learned the term 'apocryphal' in English rather recently, from westerners. We call Bright Saturday of the Holy Week 'Apocalypse Night' (Copto-Arabic
Abu Ghalimsees, from the Greek
Apokalypsis) because that is when the Apocalypse of St. John (a.k.a. Revelation) is read in its entirety in our Church. So we know 'Apocalypse' but connect it to that specific book and that specific rite, not to some division of the Bible into this type and that type of writing.
If it's in the canon of whatever autocephalous church, it's considered a done deal. And besides, for the majority of Christian history the Biblical text was encountered orally/aurally, because literacy was low and anyway the text was publicly recited (and still is, in Eastern/Oriental Christianity). It wasn't a thing to sit around and argue about, once the canon had been promulgated (whether from Alexandria, as it first was, or later from Carthage, etc). Such fights
did eventually happen later on (e.g., the Syriac Pešitta did not contain Revelation originally; I think that was only added later in the Harqelian version, 616 AD), but in a completely different context than the one in which the Protestant reformers and the Roman Catholic Church would find themselves in almost a thousand years later. So you may call them 'apocrypha', but to us they're just the Bible.
