Stylish is a free Mozilla extension that allows for the manipulation of web pages and XUL application user interfaces through the use of CSS. The "userstyles", as they are called, are available locally or from centralized web-site , which allows style sharing. It is available for Mozilla Firefox, Mozilla Thunderbird, and Flock.

Technical Details

The stylesheets made for Stylish are saved in a location, and then inserted when the page is visited. Typically, users would have to insert an !important after every rule declaration to override default styles on web pages.

Comparison to Greasemonkey

It is often compared to Greasemonkey, another Mozilla extension that allows for the client-side manipulation of web pages through userscripts, which is essentially dynamically inserted JavaScript. Furthermore, the style repository at userstyles.org allows you to add custom made stylesheets as Greasemonkey scripts.

Examples

Below are some examples of Stylish user styles being applied to web pages.
