Answer 1

Finding the extension ID

If you have many user scripts, we’ll need to find the extension ID of your user script for the next step. Go to chrome://extensions/ in your address bar, or navigate to the wrench icon, then Tools -> Extensions.

Under each extension, you’ll see an entry like ID: inoibihbncpenbmllpjoonoaadechdng. This is the extension ID. Find your script, and observe the ID.

These user scripts are usually stored in:

~/Library/Application Support/Google/Chrome/Default/Extensions

If this path makes sense, you can skip the next section. Otherwise, follow along below for more detailed instructions.

Finding your Extensions folder

Go to your user folder. You can do this by opening Finder, and going to Go -> Home. Then we want to navigate to Library/Application Support/Google/Chrome/

If you’re not using multiple Chrome profiles, at this point you should be able to just go to Default/Extensions/

Extension layout

Each extension will be in a folder, named after their extension ID. Inside this, we’ll have a version number, then any metadata files. In the latest version of Chrome, userscripts will have at minimum a script.js file and manifest.json. You’re looking for script.js, which contains the actual Javascript.
