Work Offline Page Only is a Firefox extension designed to enhance browsing by allowing users to block web pages from accessing the internet while still enabling notifications from add-ons. Unlike the built-in 'work offline' feature, which restricts the entire browser, this extension provides a more granular control over individual web pages. Users can easily toggle offline mode from a convenient toolbar button, making it simple to manage their browsing experience.

When activated, the extension ensures that all open tabs cannot send or receive network requests, allowing users to focus on local content without distractions. Despite being offline, users can still access local HTML files. Additionally, the extension notifies users of status changes through online and offline events, maintaining the functionality of connected extensions like email notifiers. This makes it an invaluable tool for those needing a focused browsing environment.
