If you use a Linux operating system, it means you are aware of its superiority in terms of security, because you needed a reason to switch from Windows to Linux. No need to have an antivrius, anti-malware installed, it is a selling point for some. Others like it because it is free.
But Ubuntu users, and derivatives, can make their operating system even harder to hack into.
Read on and try to apply some advices to Puppy or Dog OS.

Is offline cache really needed?
You may configure Firefox , in about:config, to disable the use of an offline cache.
browser.cache.offline.capacity 0
browser.cache.offline.enable false
To enable hardware acceleration in Firefox :
about:config
layers.acceleration.force-enabled setting. Double-click on the ‘false’ listed under the ‘value’ column to set it to ‘true’.

Open a terminal window (urxvt/xterm/lxterminal ... whatever) as root, open another as spot and using something like xdotool from the spot terminal window you can issue commands to set focus and use something like (don't do this) xdotool text 'rm -rf /' or xdotool key ctrl+alt+F1 ..etc. to the root terminal window. Some programs such as file managers, text editors can include options to open a terminal window, rox for instance most certainly does (i.e. root rox + spot cli can have spot invoking root actions relatively easily). Running one program such as a browser as spot within a root X session isn't secure as X by default isn't secure.Read on and try to apply some advices to Puppy or Dog OS
Windows security issues are a consequence of predominance (large numbers) and, historically, due to failing to adequately separate admin and user. Puppy is guilty of the latter.

The Firefox hardening guide is a must read for Firefox and clone users. About the only thing I didn't have was disable WebGL.
I have what is considered (by article) a hardened Firefox version here.
Just need to disable webGL in about config.
IIRC puppy has a root password manager that causes a password to be entered at every boot-up. I need a link to that thread. Thanks
