First the fog...
Assuming your usual anti fog was one that works no more the glass may be contaminated with something (sunscreen, suit snot, pond slime, who knows) Do the toothpaste or soft scrub cleaning and try again. Test it right at the sink. Chill the glass with cold tapwater and exhale a deep hot breath into the mask, it should not fog. Don't use any antifog for this test, just the dead clean mask.
If that dosen't work it may have minor surface scuffing as Damselfish mentioned, try glasswax or some very fine glass polishing compound to re-level the glass.
Now if it's leaking and you haven't messed with tension and all look for splits in the skirt or other damage includng stiffness. If you find any then forget the whole thing and treat yourself to a new mask.
Has wour weight changed? New regulator or mouthpiece? facelift? Just other potential causes.

reubenray:Just returned from Akumal and had a lot of trouble with my 10 year old mask fogging up. Had 3 different types of defoggers, but it would only last a few minutes. Also had a lot of trouble with getting water in my mask. I bought this mask from a scuba store and it has worked great until now.
Are there any fogless snorkle masks? It also seems like the mask would seal great when I first start, but when I have to take it off to defog it starts to leak. Is it time to buy a new mask? I was constantly getting water running down my throat. I first thought it was my 3 year old Ocean Master snorkle, but now I am thinking water was getting in my mask. I then would inhale the water through my nose. My nose would then run (not drip) for an hour afterward.
We have a trip planned for Tahiti in November and do not want the same problems I had at Akumal.
Any suggestions are appreciated?
