sardine allows the Mozilla user to apply customizations to all websites visited. The customizations are done by manipulating the DOM. All elements in the DOM, and all attributes of those elements can be manipulated. Any element can be changed to a different type, or hidden or an attribute removed, changed or added.
This looks interesting.
Possible applications/examples of sardine are:
* Turning off all JavaScript. (Disabling the <script> tag and onclick, etc attributes).
* Turning off all background images. (Disabling the background attribute of <body>).
* Converting blink tags into simple bold tags.
* Show non frame versions of websites. (Disable <frameset> tag).
* An ad filter. (Hide the <img> tag if its src attribute matches a certain regular expression pattern (ie. from a certain host)).
So you could apply your own display and/or security desires/requirements on any or all sites.
