Required for accurate error tracking: - Identify which tab generated an error - Associate errors with correct page contexts - Enable proper error reporting across multiple tabs Only collects minimal tab information necessary for error tracking functionality. Required to capture errors and take screenshots only when the user actively interacts with the extension. This permission is essential for: - Capturing error context in the active tab - Taking screenshots when errors occur (if enabled) - Accessing page content for error details The permission is only activated when users interact with the extension, ensuring minimal access to user data. The extension uses html2canvas.min.js, which is: - Bundled locally within the extension - Never loaded from external sources - Used only for capturing error screenshots - Runs entirely in the user's browser No external code is loaded or executed. Critical for network error detection: - Monitor HTTP error responses (4xx, 5xx) - Track failed network requests - Capture network error details Only activated during error situations and does not monitor successful requests. Necessary for maintaining extension functionality: - Store user preferences and settings - Cache error logs locally for 24 hours - Save domain whitelist configuration All data is stored locally on the user's device and is automatically deleted after 24 hours.
