Would it be worth it to disable Fedora's firewall?

The other day, I asked a question regarding Fedora's Draconian firewall (https : //ask . fedoraproject . org/question/29782/fedoras-firewall-is-slowing-networking-with-the-realtek-rtl8187/) and I was advised to disable the firewall altogether. I would use the comments feature for asking this but, according to the FAQ, I don't have enough karma points to do this.

Would I still get reasonable security out of Fedora with the firewall turned off? I am talking about the kind of security needed to perform online transactions without someone spying on me.

Thanks for any help/advice,

I wouldn't advised you to do that. No firewall means that you're unprotected from undesired attacks.

From our excellent documentation:

Just as a firewall in a building attempts to prevent a fire from spreading, a computer firewall attempts to prevent malicious software from spreading to your computer. It also helps to prevent unauthorized users from accessing your computer. In a default Fedora installation, a firewall exists between your computer or network and any untrusted networks, for example the Internet. It determines which services on your computer remote users can access. A properly configured firewall can greatly increase the security of your system. It is recommended that you configure a firewall for any Fedora system with an Internet connection.

Do read a little more if you're interested in security:

I have fixed the problem by adding my network connection to the firewall's 'trusted' zone in the KDE Control Module. Please let me know if this is a terrible idea.

That's effectively the same thing as turning off the firewall. The firewall isn't your primary line of defense against the kind of phishing attacks you describe, but it can contribute as a secondary line of defence in that case.

It's my home Wi-Fi and I'm using a desktop. Don't most of these attacks happen on public Wi-Fi networks?
