API Status Checker by Dehya

"API Status Checker" is a lightweight Firefox addon designed to monitor API requests as you browse the web. It automatically tracks API calls made during page loading and displays their status in a convenient popup.
The addon provides essential information such as the HTTP status code, API URL, and response time. Successful requests are highlighted in green, while errors are shown in red, making it easy to identify problematic APIs at a glance.
Ideal for developers and testers, this addon offers a simplified and more accessible alternative to DevTools, keeping you informed of API performance without the clutter.
