Tabs Backup & Restore - Extended oleh Warren Bank

Never lose your work again! Backup an entire browser session (all windows and tabs) both manually and automatically at a fixed interval. Drill down into each backup and inspect its contents. Give each milestone backup a descriptive name, and it becomes safe from automatic garbage collection. Restore any combination of windows and/or individual tabs. Grant the extension permission to access incognito windows, and they are fully supported for both backup and restore!

Extends the functionality of the original Chrome extension.

Does not work in Firefox for Android, due to missing APIs.
