First thing is do not think that a firewall solves all of your security problems. If, for example, you request the download of some malware, the firewall 'knows' that it is your request and so lets you do it... And it does nothing to protect against phishing.
So the attitude 'nothing can get me, I've got a good firewall' is somewhat dangerous. You still need normal good security practices.
Secondly, be aware that firewall commonly means something slightly different on windows and linux. On windows, a firewall is a gui and firewall wrapped up together and is sometimes bundled with anti-virus too. On Linux there is a distinction between iptables (really, a firewall programing system) and a gui that you might choose to use to simplify the configuration of the firewall proper.
As commented earlier, the firewall itself is a high-quality, serious bit of kit. The guis make set up of the firewall in some ways simpler, but one of the trade-offs is that they don't always give you all of the versatility (most people don't need it) of the underlying firewall system.
