## Description

SingleFileZ is a powerful Firefox extension designed to save entire web pages, including CSS, images, fonts, and frames, as a single HTML file that doubles as a valid ZIP archive containing all the page resources. It offers an intuitive workflow where users can save the current tab, selected content, frames, or links through the toolbar button or context menu.

Beyond simple saving, SingleFileZ supports processing multiple tabs simultaneously, auto-saving pages after loading, and uploading files directly to cloud services like Google Drive and GitHub. Users can also utilize customizable shortcuts (e.g., Ctrl+Shift+Y) for quick saving. For detailed configuration or troubleshooting, comprehensive documentation is available through its GitHub project and integrated FAQ. This makes SingleFileZ an indispensable tool for efficient web archiving and offline browsing.
