I don't trust this app. After installing the extension, it immediately wants to download dmaster.exe from a site ONLY IN RUSSIAN which could be a trojan. I have reported to chrome web store for review and have not run dmaster.exe as it is very suspicious. Extension should not need extra executables.
Intercept downloads for Download Master, download a file or a group of files from the context menu
The extension adds the ability to download using Download Master specified file or group of files from the browser's context menu
It also enables or disables browser integration and allows setting the minimum file size from the extension options
