DV PM Checker is a free Chrome extension developed by DimonVideo. It is designed specifically for users of the DimonVideo.ru website, providing them with notifications about personal messages. This extension runs in the background and continuously checks for new messages, displaying a pop-up notification whenever there is a new message.

One of the key features of DV PM Checker is its flexibility. Users can set the interval for automatic message checking, ranging from 30 seconds to 30 minutes. Additionally, users have the option to disable the pop-up notifications if they prefer. The pop-up notifications automatically disappear after 5 seconds, allowing for uninterrupted browsing.

DV PM Checker also allows users to customize the action that occurs when they click on the extension icon. Furthermore, users can choose to disable the sound notification and even replace it with their own sound file, which can be placed in the extension's folder.

With its convenient features and seamless integration with DimonVideo.ru, DV PM Checker is a valuable tool for users who want to stay updated on their personal messages without constantly checking the website.
