With 'free wifi' most harmfull stuff is not actually related to your firewall (unless you block everything, which makes no sense).

A person who owns that wifi network in one way or another can :

1. Use fake DNS and create fake pages for folks inside that network.
2. Sniff network traffic, especially unencrypted/poorly encrypted traffic and analyze it or/and save it for later (perhaps even years, to brute force it later when he gets a new gpu Smilie )

A lot of other things for an imaginative mind.

Conclusion is if the for anything but casual surfing (no banking, no credentials input), unless you know for a fact that no such things exist in that network.
If using be sure to check the certificates of pages you are leaving credentials at, and use strong encryption.

Hope the helps
Regards
Peasant.

NAME
WiFi Radar - utility for managing WiFi profiles SYNOPSIS
wifi-radar [OPTION]... DESCRIPTION
WiFi Radar is a PyGTK2 utility for managing WiFi profiles. It will look for the config file in /etc/wifi-radar/wifi-radar.conf. You can change that in wifi-radar. If the configuration file does not exist, it will create it, so you must always run it within a correctly permitted account (as root or use sudo or pam). Recent versions partially implement WPA-TKIP with wpa_supplicant. You need a running wpa_supplicant installation with a /etc/wpa_suppli- cant/wpa_supplicant.conf file. Then by setting in your /etc/wifi-radar/wifi-radar.conf file the "use_wpa = yes" option and "wpa_driver = ipw" for example, wpa_supplicant will be launched when you connect using this profile. But currently you can't set your wpa_supplicant options like the psk, proto, key_mgmt etc. using wifi-radar. Your wpa_supplicant configu- ration file should be set and tested already. If you have different networks set in wpa_supplicant.conf, then you can switch using wifi- radar. The wifi-radar script accepts the following command-line options: OPTIONS
-v, --version for printing the version. FILES
/etc/wifi-radar/wifi-radar.conf See for more information. BUGS
Probably lots! Because of repeated scanning, WiFi Radar is very power consuming. Please report bugs to the mailing list <https://lists.anl.gov/mailman/listinfo/wifi-radar> MORE INFORMATION
