MeddleMonkey (fork Violentmonkey with some features) is the most popular user script manager, with over 4 million users, which supports for Chromium-based browsers like Opera and Chrome.
Even though some of the supported browsers have built-in support for custom scripts, the MeddleMonkey browser extension will provide much more convenient management of these scripts. This extension supports features such as easy script installation, automatic update checks, a simple overview of the scripts running on the tab, and has a built-in editor. In addition, there is a good chance that incompatible scripts will work fine when using MeddleMonkey.
MeddleMonkey Chrome extension greatly simplifies the process of managing custom scripts. The MeddleMonkey icon in the upper right corner shows the number of running scripts, and clicking on it opens a list of already running scripts and a list of scripts that can be run on this page.
It only takes a minute to install the extension, so give it a try!
