## Description

Caps Lock Notifier is a handy Chrome extension designed to improve your online security experience by clearly indicating when Caps Lock is activated within password fields. By adding an intuitive icon next to password inputs, it prevents common typing errors that occur due to unintended use of Caps Lock. Hovering over the icon displays a tooltip saying `CAPS LOCK is on!`, ensuring users are immediately aware of their keyboard state.

This extension respects user privacy, requiring only permission to access page data to detect password fields across websites. It does not collect or store any personal information. For transparency, its source code is publicly available on [GitHub](https://github.com/ItsNickBarry/caps-lock-notifier). Caps Lock Notifier is a simple yet effective tool to enhance password entry accuracy on any website.
