Sorry I just found out this way it actually works. But the problem is when I trying to look up address manually, not by msg.sender.

Code:

mapping (address => uint) count;

function set() public{
    count[address(0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe)] = 3;
}

function get(address _address) public view returns(uint){
    return count[_address];
}

I called set function and when I pasted the same address into get function the result was 0.

    You should add your source code – Gabe Mar 19 '18 at 14:34
  • The 20-byte address code would be packed into a 32-byte word, possibly with other data depending on the contract and what the compiler decides to do with it. It's not clear why you're working at this level or why it's a problem, when Solidity will happily decode it for you. Please include your contract. – Rob Hitchens - B9lab Mar 19 '18 at 14:56

Add the address in the field with quotation marks "0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe"

It works for me.
