Internet experience by adding features to previously text and image only
sites. As with all things, they have their drawbacks, too, which can be
With these settings applied, Mozilla should protect your online security
and privacy even better. But as I said in the beginning: The safe use
of the Internet is always also the
(i.e. the Browser) and uncheck (disable) it for Mail & Newsgroups.
The reason why I recommend this is that I see no reason whatsoever for
Javscript in mail and newsgroup messages besides using a script to
data from a remote server (verifying that you have read the message) or
to do things you neither need nor want them to.
- The recommended "Allow scripts to" settings are:
Uncheck (disable) "Move or resize
existing windows", "Raise or lower windows", " Change status bar text" (this will help protect you from Spoofing, i.e. sites pretending to be another site) and "Hide the status bar".
Check (enable) "Change Images" (this is e.g. used for mouse over
effects), "Create or
change cookies" and "Read Cookies". All other features will (in
my opinion) neither hurt if selected or deselected.
- The recommended "Enable plugins for Mail & Newsgroups" setting is:
Uncheck (disable) "Enable plugins for Mail & Newsgroups", as again, I see no need for plugins in mail
and newsgroup messages, but I do see potential for misuse.
This means: Be careful with the attachments you open (when in doubt,
ask the sender what it is he sent you), use an Antivirus program and a
personal firewall. Common sense and personal firewalls are free
An interesting extension for Mozilla is Prefbar. It adds a configurable toolbar that allows you to toggle many of the settings (plus other settings) that were mentioned in this tutorial. To see an example what prefbar can look like, click here (opens in a popup window)

This article explains how Mozilla's automatic Spam filter works and summarizes Hard Tecs 4U's review of it.
- Browser Security Test. This site will scan all popular browsers for security vulnerabilites. It's a good way to see if your security is up to date and to compare the different browsers you have.
- Antivir. This company offers a free (for personal use) Antivirus program.
- Zone Labs. Zone Labs offers the popular firewall Zone Alarm. Zone Alarm basic is available for free.
- Ad Aware. Ad Aware is a free program that scans your PC for Adware, Spyware, Tracking Cookies and more. This is highly recommended if you have previously used Internet Explorer or experienced unexplainable popup windows and a slowdown in your PC's speed.
