Well, you'll never be safe, that is for sure
. Security is always a
What kind of environment are you using your computer in? The firewall is
probably only necessary and helpful when you are connected to the
Internet directly. As soon as you are behind a router its not that
important any more, because your PC can't be reached directly anymore.
So, it may be helpful in public sites for instance.
However you should be aware of the fact that there are various other
threads, which are most likely more often exploited. So as soon as you
are using your browser you live in danger of becoming hacked by some
scripts or exploits within various engines and/or plugins you run.
On the other hand its a big improvement in security when using Linux
instead of Windows, because as long as Linux is in a minority there
won't be as much hacks/exploits for it. It may be that Linux is more
secure than Windows in general, but that is another question I don't
want to raise.
I think the biggest thread actually is to use Adobe's plugins, namely
Flash and Reader. Because they are so widely spread, they get exploited
very often. I don't know exactly whether the Linux versions of these
plugins are any better of, but for instance the 64-bit version is not,
because its in a beta state and doesn't get updated that often.
browser crash. Probably there are also some bigger threads than that
All in all: Security is a big and complex issue and you're never 100
percent safe. You just make trade offs between security and convenience
and/or usability. But you should be relatively safe by using Linux, at
least by now. The firewall itself doesn't protect you in any sense from
exploits within your browser, but can provide some kind of security,
especially in situations where you are connected directly to the
Internet or when connected with other clients you don't trust or know.
