Firewall recommendations for Ubuntu OS?

[Rosiv]

Reason: I want to use my Ubuntu laptop in coffee shops and other public networks, but I do not know much about security. I have always let "Windows firewall" and my router do all the "security" on my windows machine.

Any advice for firewalls? I have googled some, but they seem very rigid. Any general advice for public use of a Ubuntu machine is also appreciated.

Ubuntu has firewall built in called uncomplicated firewall (ufw). To get a graphical front end for this firewall, open a command line and enter the following

sudo apt-get install gufw

to activate gufw System->Administration->Firewall configuration

Personally I use iptables so I don't know the settings so I can't help you beyond that.
