Macro Selection Page

Your .wwwshield/rules configuration file contains a number of predefined functions that can be enabled or disabled. Select the functions you want by checking their boxes in the left column, then press the Confirm button. Note that changes may not have an immediate effect when reloading pages because the browser may be reloading from its cache.

Image-free URLs
All web pages whose URL contains one of the words in the following list will be shown without any images. This is useful for search engines and other text-oriented services.
Remove banner ads
All pictures and all hyperlinks from the list are replaced with a short notice, [deleted]. Any link, image, or form action that contains one of the words in the list is killed.
Cancel ad loading
The previous macro cannot catch banner ads that are constructed on the fly by JavaScript and other applets. This macro is the second line of defense. If the previous macro cannot hide the ad from the browser, this macro prevents the data transfer. It uses the same word list. This may disrupt or truncate the page layout, for example on www.userfriendly.org which surreptitiously accesses ad.doubleclick.net.
Remove banner images
Advertising agencies have established standards for banner image sizes. This macro eliminates all images of the standard sizes 468x60, 234x60, 156x60, 400x50, and 130x80. It relies on correct size markup.
Web bug killer
Web bugs are tiny, usually invisible images that exist only to cause the browser to generate data transfers to ad servers. Due to a HTTP design bug, web bugs can, and usually do, carry cookies.
Cookie Killer
Commercial sites use cookies to store personal data on your system, and use it to identify you later. Many commercial sites also share cookie data. Most people don't like to be tracked in this way. This function suppresses both incoming and outgoing cookies except those from URLs that contain any of the words in this list:
Referer fields
When accessing a document, the browser always sends the URL of the previous URL along with the request. It's called the ``referer'' because it lets the server know which link was followed. Some sites compile your ``clickstream histories'' from referers. You may not want to be tracked in this way, and it can be dangerous if the previous URL contained arguments such as your credit card number in extreme cases.
Last-Modified fields
Since cookies got such a bad name, people have started tracking users with cache timestamps. This macro eliminates the timestamps that identify you, but also causes your browser to reload pages instead of fetching them from its fast local cache.
Netscape what's related
Netscape 4.0.6 and up have a ``What's related'' button that, depending on browser configuration, sends a trail of visited URLs to Netscape, including internal ones. The privacy implications are grave. This macro kills all connections to www-rl*.netscape.com [Ref]. This macro is experimental.
URL sticker
Print the URL at the bottom of every page. This helps finding the page later, after being saved or printed. It may confuse pages with carefully crafted frame layouts.
Change user agent ID
When connecting to a server, your browser identifies itself to the server as . Some servers use this to keep statistics. The NASA Squid proxy, for example, claims to be ``Nutscrape/1.0 (CP/M; 8-bit)''. This function replaces the user agent ID with:
No Scripts
Disable JavaScript and other forms of embedded code, as recommended by CERT (Computer Emergency Response Team, the independent authoritative computer security organization) in 2/2000. Malicious code frequently manages to circumvent browser security and play havoc with your computer. Note that this macro may make pages that intertwine Javascript with frames come up blank.
No fonts
If your X server does support TrueType fonts, your browser probably renders everything in microscopic sizes. This macro removes all font face setting (but not font size settings).
No new windows
Some links pop up new windows when you click on them, because the designers can't bear the thought that their precious page gets displaced from your screen. This macro forces the link to open in the same browser window.
Unblink
Most people absolutely hate blinking text. This function replaces blinking with boldfacing.
Bigger fonts
An amazing number of websites use unreadable microscopic fonts. Recommended minimum sizes are 2 or 3. This macro increase all font sizes to at least:
