Yup I just keep mine off, except of course with the same FTP problems others have described, I just turn it off breifly for work in dreamweaver & such
 
I mostly keep it off since I'm behind a hardware firewall. And at school I just forget to turn it on most of the time.
 
I used to keep mine on all the time, but I was having problems with my internet connection on my 15" powerbook. I went through all sorts of crap to fix it, and finally someone suggested turning it off, I did, and now it runs smoothly and has for a while....--knocks on wood--.

I still have it turned on in my PowerMac and iBook though. I don't know why there would be a difference, but whatever.
 
Haven't used it for a while, no reason for me to.

I just trust the firewall on the router to do its job.
 
Mine's on all the time. I've just opened the ports for a couple of services. I just use the built-in System prefpane, haven't bothered with the whole ipfw config from Terminal, yet, anyway...

It doesn't interfer with ftp in Terminal, nor in Cyberduck or Dreamweaver as I've sat that those to use passive ftp. 🙂

Same here – I just have mine switched on, with a couple of ports open, and don't worry unduly about it.
 
I have mine on and I have Stealth Mode on. I figure that if it's there, why not use it? I don't have any problems with it.
 
i used to use Zone Alarm on my pc until I got a sonicwall router. Since I got my ibook after that, I have never used the Mac firewall.
 
I have it on but it chokes while FTP'ing so I turn it off for that. I have a port open for my torrents. 😉
 
I've only turned it on when I've been on untrusted networks. Really though, at the moment, I don't think it's terribly necessary, but *shouldn't* hurt in most cases to have it on all the time.
 
I have it off, because I have a hardware firewall.

I despise the firewall built into Trend antivirus on Windows - it turns itself on without asking. I remember installing Trend AV on a headless system via remote desktop. Near the end of the installation, the firewall automatically enabled itself and therefore blocked my remote access 😡

I was also trying to set up a network for a friend. I got it network all working, then the next day they ring up and tell me they can't see the other computer. It turns out that McAfee's firewall automatically switches itself back on when you reboot! I ended up having to uninstall the thing to stop it from loading (the system is not connected to the Internet).
 
Even though I have a hardware firewall I keep the OS X one on, well its there and its not interfered with anything I use
 
I have it on with only the ports I need open. My school has a firewall, but I don't know if it protects the network internally. I work for ResNet so I know what gets on students systems. At home I the DSL modem I use has a built in firewall, but its so confusing to configure that I gave up.

Hardware firewalls are better, but when you can't control them, I start to feel uncomfortable.
