# 1Extn Script Library

Documentation last reviewed: 2026-10-03

The 1Extn Script Library provides optional `.1extnscript` downloads that open in 1Extn for review and saving. These downloads expand the app without replacing its built-in Safari tools, starter scripts, or Actions interface.

## Import Flow

1. Choose a script from the official website.
2. Download its `.1extnscript` file.
3. Open the file in 1Extn.
4. Review the script code.
5. Save it to My Scripts.

Imported scripts do not enable Auto Run automatically. Users decide whether a trusted script should run manually or automatically on selected Safari websites.

- Review code before saving or running it.
- Test a script manually before considering Auto Run.
- Enable Auto Run only for scripts and websites the user understands and trusts.
