Got a website you want to the change look of, or a part of your browser you'd like to tweak? Style 'em with Stylem, the userstyle manager for Pale Moon, Basilisk, plus other XUL-based applications!
Stylem, forked from the last fully open source release of Stylish for Firefox (2.0.7), lets you create custom CSS files for any element of any website or any part of your browser. You can install these from the Add-ons Manager, either by pasting the URL of the CSS file into the "Install from URLs" button, or by pasting the CSS itself into a new style.
Usage of Stylem remains much the same as Stylish. For FAQs and general information, please consult the Stylem wiki. Internally however, a few things have changed such that extensions designed to work with Stylish may not work with Stylem and should be re-adapted where required.
If you are a previous user of Stylish, please disable or remove Stylish before using Stylem, as due to the way these both deeply integrate with the Add-ons Manager they are not compatible with each other and will result in issues. Any styles saved in Stylish will be transferred, as both Stylish and Stylem use the same storage format. Settings from Stylish itself will not be transferred however, as Stylem uses its own settings instead (extensions.stylem.* in about:config).
