TabMerger is an open-source tab management extension for Chrome, Firefox, and Edge.
With a single click, you can have all your tabs in a single place, where you can then re-arrange them into appropriate groups, delete extra/unwanted tabs, customize group colors, and so much more. All tabs that are merged into TabMerger are stored internally for you to use at a later time, even when you close the browser window. Lots of analytics are provided to keep you informed about the state of your tabs.
