I buy tortillas in bulk (36 to 48) at a time.
I freeze them because even our family of 6 won't go through them fast enough if left in the refrigerator!
I stack them with individual freezer wax paper between the tortillas (get them at warehouse stores such as costco) and then place in a plastic freezer bag or in a plastic storage container.
I THAW them in the microwave 6 at a time, papers removed, then wrapped in a SLIGHTLY damp kitchen towel.
30 seconds on high does it for the stack.

If you are freezing the tortillas yourself and don't mind putting in a little extra work in the beginning to get more convenience later, I would separate the tortillas with waxed paper (actually I use the paper sheets that are waxed on one side, intended for bakeries).
What this buys you is the ability to pull out one or two tortillas as you need them.
They will defrost just fine in the pan that you are going to warm/brown them in anyway.
If you customarily run through a dozen tortillas, then you probably don't want to bother.
But if that is the case then you probably aren't freezing your tortillas in the first place.

The microwave is good for this sort of thing.
Just wrap them in a towel to hold in steam and go for a couple minutes until they are soft.
Or if you aren't too worried about plastic toxicity, you can put a few holes in the bag they came in and do it right in that.

If you've got the time, just put them (back) in the fridge for a couple of days.
I always keep some frozen (mostly because I have more room in the freezers than in the fridge).

I put them directly on the stove burner and flip with tongs.
Works great, they taste better this way.

You can put them in the fridge for a couple of days, thaw them in the microwave six at a time or just defrost them in the pan or directly on the stove burner. You can defrost them in the fridge, the microwave or in a pan.
Defrost them in the microwave a few at a time. Defrost them straight in the pan. Put them in the fridge for a few days to defrost.
