About this extension
Environment Highlighter helps you stay oriented in your browser by displaying a customizable banner at the top of websites that match user-defined URLs.
You can define your own:
• Matching URLs (full or partial)
• Banner text
• Banner color
Perfect for developers, testers, system administrators, or anyone switching between multiple environments like production, staging, or test. The banner helps visually separate sites that may look identical but behave differently.
All settings are saved locally in your browser and never transmitted.
No tracking, no external servers, 100% local.
