User scripts are powerful customizations, authored by the community, that allow registered Wikipedians to change Wikipedia's interface beyond the options available in preferences. This page provides a list of available scripts and instructions on installing them. User scripts are written in JavaScript.
Many of the most popular scripts become gadgets, and are subsequently removed from this page. You can enable them via Preferences - Gadgets. It is recommended that you check there first for any tool you might be looking for, since gadgets have been widely tested and proven useful and reliable.
Most scripts are designed and tested primarily with the Vector skin, Wikipedia's current default.
How to install user scripts:(Simple method for scripts located on English Wikipedia)
First, make sure you are registered and logged in. Only logged-in users can install scripts.
Click the superscript link next to the name of the script you want to install and follow the instructions in the footnote.
If there is no superscript link next to the name of the script, then follow the link to the script's documentation and look for installation instructions there.
After you copy the necessary code to your common.js file as instructed in the footnote/documentation, save the page and bypass your cache to make sure the changes take effect.
Automatic installer:Script Installer makes script installations fully automatic. The installer itself must first be installed manually. Afterwards, scripts can be installed with a single click.
