To have the safest browsing experience, you can run Firefox in a 'sandbox'.
But first you have to:
install Fedora 14
(not tested in Fedora 13)
yum install policycoreutils-sandbox
(this needed to supply 'sandboxX.sh' )
create a directory 'sehome' in your home directory(you can use a directory with a different name if you so wish)
The following article explains how run Firefox in a very secure environment:
Now, Firefox is pretty useless without network access. The good news is that you have sandbox types that allow for Web browsing. Here's what you want to run to get a Firefox session going:
sandbox -X -H sehome -T tmp -t sandbox_web_t firefox
Here you're adding two things — the
-X option, which tells SELinux "hey, I want an X sandbox," and the type (
-t) option which specifies a set of policies that offer the services (like networking) that Firefox needs to operate in a sane way.
