Session Alive is a Firefox extension designed to prevent session timeouts on websites requiring authentication. This subscription-based tool automatically keeps your session active by reloading the website in the background, eliminating the need for manual refreshes even during periods of inactivity. It supports Multi-Account Containers, allowing users to manage multiple sessions seamlessly. Users can easily set up rules for specific pages, ensuring that their sessions remain alive without interruption.

In addition to background page requests, Session Alive offers a foreground page reload option to counteract websites that implement JavaScript idle timers. Users can customize settings to suit their needs, including setting intervals for background requests and receiving notifications about the status of their sessions. Advanced users can also override idle timers for enhanced control. The extension is open source, encouraging community contributions and transparency.
