For every page you request with your browser, FilterProxy will compare its URL to the 'URL regexp' list above. If one (or more) match, it will apply the filters listed for that regexp. A regexp is a Regular Expression, and gory details can be found by running 'man perlre'. The basics are summarized below. These regexps are case-insensitive.

If more than one regexp matches your URL, each of the configurations is passed to the respective modules. This acts like an AND operation in that all the filters (and config for each filter) will be applied to pages matching those URL regexp's.

If you wish to have a module not be applied for a particular site, when it would be applied normally, create a URL regexp for that site, select the module you don't want applied, and click "Delete". The module will show up in the list looking like -(DeAnim) and that module will not be applied to any site that matches the corresponding URL regexp.

Regular Expression Overview

Hopefully you get the idea. If you need more info, consult perl's "perlre" manual page.
