Can't be done. 

The switches must form a logical stack.  Like a 2960S or a 3750, 3850 or 3650.

Ok, look at this from this point of view ...

If you have two 2960S/X, 3750, 3650 or 3850 and they form a single switch, then you can easily form an etherchannel even though the NICs are going to two physical switch. 

How can you form an etherchannel from two plain-2960 switch to a single server?  You can't.

thank you very much

also i noted that there is no mac - address come from the 2nd switch to the first FW becuase i though that the 2nd link whiches go to the 2nd switch is active , it was and still stand by the the default behavior of thr redundant interface on the FW

but i think to fix that work with 2960S Stack with ethernetchannel on the firewall what do you thing

That's correct.  The NIC ports need to go to a single LOGICAL switch.  If you stack, say, two or more of their 3750, 3650, 3850, 2960S/X, then what you are doing is creating a single LOGICAL switch.  This will enable etherchannel across multiple PHYSICAL switch.
