Mike Conley (:mconley) ⚙️: "Keeping open too many duplicate tabs? Me too. #Fi…" - Mozilla.social

Keeping open too many duplicate tabs? Me too. #Firefox Nightly now has an option in the tab overflow menu (that's the down arrow near the top right of the window) to close all duplicate tabs in the window.

For all duplicates, it's the last active tab that'll remain open.

Go reclaim that memory and CPU!

Finally duplicate tab management comes to Firefox natively.
