The story behind the Firefox session manager built for productivity enthusiasts.
To help people work more efficiently by providing the best session management experience for Firefox users.
Sessionaire was born out of frustration. Like many power users, we found ourselves juggling dozens of tabs across multiple windows, only to lose everything when Firefox crashed or when we needed to restart our browser. Existing solutions were either too complex, too slow, or required sending our data to external servers. We wanted something different: a fast, private, and elegant session manager that just works. So we built Sessionaire from scratch using pure vanilla JavaScript—no frameworks, no dependencies, no tracking. Just clean, efficient code that respects your privacy and gets out of your way.
Your data stays on your device. We don't collect, track, or sell any information. Ever.
Zero dependencies means lightning-fast performance. No bloat, no slowdowns.
Clear about what we do and don't do. No hidden features, no surprises.

All session data is stored locally in your browser using Firefox's built-in storage API. Your data never leaves your device.
We don't use any analytics, tracking pixels, or third-party services. We have no idea how you use the extension.
Sessionaire doesn't make any network requests. It works entirely offline once installed.
We only request the permissions necessary for session management: tabs, storage, and sessions. Nothing more.
