# Startup Failed: User Script Permission Required

If your browser extension fails to launch and displays a message about needing user script permission, it typically means the necessary user script functionality has not been enabled in your browser.

Please follow these steps to resolve the issue:

**Step 2: Enable Developer Mode**On the "Extensions" page, please enable the "Developer mode" switch, located in the top-right corner.For Chrome, this switch is usually in the top-right corner. For Edge, it's typically in the bottom-left.
