FireZard.swapTokens(uint256) (#732-742) performs a multiplication on the result of a division:
-transferToAddressETH(developmentAddress,transferredBalance.div(_liquidityFee).mul(developmentDivisor)) (#740)
Consider ordering multiplication before division.

Ensure that all the return values of the function calls are used.

Additional information: link
FireZard._maxTxAmount (#486) is set pre-construction with a non-constant function or state variable:
- 101 ** decimals()
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.7 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
