## Description

Offline Caching is a powerful Chrome extension that lets you enable offline access on virtually any HTTPS website or web application. By injecting a dedicated Service Worker into your chosen sites through a simple popup menu, this tool ensures you can continue browsing and using apps even without an Internet connection. Designed to work seamlessly with standard web technologies, Offline Caching enhances usability, especially when you're offline or in areas with unstable Internet. Note that it supports HTTPS sites only and does not operate in private browsing mode due to Service Worker constraints.
