Simple, lightweight, and very reliable for tracking server metadata.
If you are a developer, researcher, or just someone who needs to verify exactly when a webpage or a file was last modified on the server, this extension is perfect. I’ve used a few other timestamp utilities, but they often try to inject heavy scripts into pages or get blocked by security policies. This tool works cleanly in the background without any fluff. [1]
What makes it better than the alternatives:
Instant page checks: You just click the extension icon and it immediately fetches the real Last-Modified HTTP header of the active tab. It also intelligently ignores system or store pages to prevent useless error pop-ups. [1, 2]
Automatic download analysis: The moment you start a download, a native system notification pops up showing the file name, actual size, and server modification date. It is incredibly helpful for checking if you are downloading the latest version of a file. [1]
Smart local history & privacy: It displays your last 5 downloads right in the popup, allowing you to copy the original URL with one click. Best of all, it respects your privacy: it runs 100% locally and if you clear your native Chrome download history, this extension wipes its own cache automatically. [1, 2, 3]
