Env Tab Prefix от Irusu

Env Tab Prefix adds a configurable prefix to the page title based on the current URL. With this you can quickly identify environments such as dev, staging, or localhost instantly.

You can define custom rules using hostname or full URL matching (startsWith, endsWith, contains, equals, or regex). Each rule can assign a custom prefix like [DEV], [STAGING], [LOCAL], or any label you prefer. The first matching rule is applied.

This extension is especially useful for developers working with multiple environments, helping to avoid confusion and mistakes when switching between production, staging, and local systems.
