Alright, I was bored and saw that nobody had answered your post so I did a little investigating for you!
On the left you have to click on 'Our Services' and then 'Aircraft'. After that you will see a screen which lists the current number of Air France aircraft in Long/Medium/Short Haul. At the top however, in smaller dark blue writing, is a title which says 'aircraft' and below that in the same colour blue 'Boeing' and 'airbus'. Click on which aircraft company you are interested in seeing seat-maps for and then select the aircraft type!
1. Click ---> 'Our Services'
2. Click ---> 'Aircraft'
3. Click ---> 'Airbus' OR
4. Click ---> *select aircraft type*
I'm not sure whether these are reliable or not as I have never flown Air France, but since it is on their site I don't expect it will be too far off/ out of date.
Also not ALL
aircraft have seat maps. For example I do not believe that there is one for the A330.
Hope this helps!
