Martin Luther removed these books when he first translated the Bible into German. He did not consider the books to be consistent with his theology.
Regarding Jasher, it is not included in any canon in existence, and Enoch only a few though Enoch was considered sacred by the Essenes who created the Dead Sea scrolls.
Jasher is interesting because of some seemingly significant characters who are glossed over in the Bible. There are two explicit references, but there are also many other implicit ones. Story lines in the Bible that make little sense on their own, but are clarified in amazingly consistent ways in Jasher, making the incomprehensible suddenly understandable. (Albeit these are storylines that are not particularly noteworthy in theology, but are historically.)
Jasher 2:26-35 --> Genesis 4:19-24 (Details of Lamech's extended family, and the killing of two men was accidental)
Jasher 3:27-38 --> Genesis 5:24 / Hebrews 11:5 (Explains what happened to Enoch)
Jasher 5:6-9 --> 2 Peter 2:5 (Genesis does not refer to Noah as a preacher as per Peter, but Jasher does, and Noah was helped by Methuselah)
Jasher 11:6 --> Genesis 14:1,9 (Nimrod goes by the name Amraphel in Genesis)
Jasher 34:32-35:25 --> Genesis 34:30,31 (After Dinah was raped by a Canaanite prince, and Simeon and Levi kill everyone in Shechem, there are no apparent consequences in Genesis other than Jacob's rebuke. An aftermath ensues in Jasher with the Canaanites, grossly embellished in alterations I believe, but still making more sense.)
Jasher 73:30,31 --> Numbers 12:1 (Moses wife was a Midianite. Why does Miriam complain about Moses Cushite wife? Jasher explains the story for Moses missing 40 years after fleeing Egypt.)
Jasher 75 --> 1 Chronicles 7:20-23 (Descendants of Ephraim are killed in a battle with Gath over a cattle dispute. No explanation in Chronicles, but the story is complete in Jasher.)
Jasher 79:27 --> 2 Timothy 3:8 (Jannes and Jambres mentioned by Paul don't exist anywhere else in the Bible, but they are in Jasher.)
Jasher has some stories about Abraham's early life that are not in the Bible, but are in the Qu'ran. (Written many centuries earlier) It is unlikely that a Jewish scribe, even if he were altering a Midrash would add information from a Muslim source unless both came from an even earlier document. Many Islamic writings appear to come from earlier Gnostic teachings.
