Seeds stored in a refrigerator can last much longer than seed stored at ambient temperatures; but as already mentioned, they should be in a sealed container to exclude moisture. A mason jar works well, and the desiccant packets mentioned by Xiangirl offer extra protection.
Frozen seed lasts even longer, sometimes for decades. Like refrigerated seeds, frozen seeds should be stored in an air-tight container.
Before being frozen, though, the seed must be dried to a very low moisture
level. For me, that is as simple as leaving the seed on trays until the
indoor humidity has dropped in December; but in humid areas, it may be
necessary to use desiccant (drying agent) in a jar to dry the seeds. A good rule of
thumb is that if you can bend the seed without breaking it (for small or
thin seeds) or if the seed does not shatter when hit with a hammer (for
large seeds like beans, peas, or corn), then the seed needs further
drying. I can't over-emphasize the importance of properly dried seed, regardless of how the seed will be stored.
For both frozen and refrigerated seeds, the container should be allowed to warm to room temperature before removing seeds. If exposed to the air while still cold, moisture could quickly condense on the seed, which could kill the seeds, or severely reduce their viability. It is worth mentioning that seeds received via the mail in Winter can be damaged the same way, if opened while still cold.
I have had good results storing most seeds in zippered plastic freezer bags, in a cool part of the house. It helps to squeeze out as much air as possible after each use, by rolling up the bags & packing them tightly into a box or drawer. In areas with low indoor humidity & moderate temperatures, paper envelopes stored in a cool dark location may work well for several years.
Part of seed saving is learning what works for you & what doesn't. Hopefully you find out what doesn't work in a way that avoids disappointment. When in doubt, do a germination test well before planting time. That way if the seed fails, you still have time to look for more seed, and don't end up with a dead spot in the garden. Ten seeds is a good number to test, provided there are enough to spare.
Elen, it looks like most of your seeds are in small zip lock bags. If they were only in the fridge for a short time, chances are that most of them are OK... but I would still recommend doing a germination test for anything which you intend to plant this year. If you get failures, it might be advisable to test the remaining varieties as well.
Nice labeling, by the way. ;-)
