Work Offline

Brings work offline and online in the web page level to your browser

What is Work Offline?
'Work Offline' is a handy Chrome extension specifically designed to make the web browsing user experience more efficient. It provides the user with the ability to toggle between online and offline modes, with the offline mode preventing web requests from being sent or received by web pages. Notable features include the ability to still use web-based extensions while in offline mode, browsing local HTML files offline, and tab-specific offline settings. It also supports navigator.onLine, 'online' and 'offline' events, and respects global offline and online browser level events.

This extension brings "Work Offline" button to your browser. When the extension is in the offline mode, no web request can be sent or received by web pages. Note that still, your extension can use the internet. So let's say you have a web-based email client and an email notifier extension. The web-based one is disconnected, but the extension one is connected.


  1. You can enable and disable the offline mode right from the toolbar button. This is a toggle button.
  2. If you have open tabs, those tabs cannot send and receive network requests in the offline mode
  3. You can still browse local HTML files while you are in the offline mode, though these pages cannot anything to any web servers

Change Log: version 0.1.2

  1. Offline mode per tab. You can now use the right-click context menu item for page action to make a single tab or multiple tabs go to the offline mode. It is still possible to use the toolbar button to make all tabs work in offline mode too. version 0.1.3
  2. supports navigator.onLine
  3. supports "online" and "offline" events
  4. respects global offline and online browser level events

Thanks. I Like it so much. It's work like a charm

Basically useless for development. It won't load anything even if it's local. Closing the browser would be a good replacement for the functionality this extension offers since you can't do anything once you enable it.

It was quite useful for debugging with pwa development, but now its not showing the page when offline mode is activated
