Save Tabs for Firefox

A Firefox extension that saves your open tabs so you can close them with a clear conscience and bring them back later, one at a time or all at once.

Features

• Save the tabs of one window, or the tabs of every open window in one go.
• Rename saved entries so a set is recognisable later.
• Open a single saved tab or restore the whole set. Tabs saved from several windows reopen in separate windows, laid out the way they were. Restored tabs do not preload, which keeps sites from seeing a burst of bot-like requests.
• Export a saved set as a text file or straight to the clipboard.
• Export everything saved over time as JSON, or import a JSON backup; handy when setting up a new browser or migrating machines.
• When saving into an existing parent, choose whether to replace the tabs or add the new ones.
• An option to hide page titles in the link rows gives the list a cleaner look.
