URL Warning Banner od Angel A C

This extension by default does nothing. It simply shows a warning banner for defined URLs added in the config.

Features:
- Configurable: multiple URLs and can use wildcards
- Banner is added and removed automatically as you navigate in and out of configured URLs
- Works in Single Page Apps — the banner updates as you navigate between client-side routes, without a full page reload
- You can dismiss and close the banner

Usage:
1. Click the extension's toolbar icon (or open Add-ons → URL Warning Banner → Preferences) to open the settings page.
2. Add one URL or pattern per line. * is a wildcard, and a pattern also matches sub-paths. Each line must include a scheme, e.g. https://.
3. Save. The banner appears automatically whenever you visit a matching URL and is removed when you navigate away — including client-side route changes in single-page apps.

Example:
https://example.com/production/*
