Tab Saver by Breno RdV

"Tab Saver" is a lightweight and user-friendly Firefox extension designed to help you save all your open tabs and (optionally) a description. That is saved as a markdown file in your computer so you won't lose those tabs.

We respect your privacy: all the data is stored locally, no user data is collected, shared or uploaded anywhere. The functionality extends across all browser windows, ensuring all your workspaces are captured.

The extension is easy to install, operate, and it integrates seamlessly into your browser. It's been designed with simplicity in mind and a few essential features.
