Four ways to get a handle on your tabs
Each one works on its own, so you can turn on just what fits.
Duplicates
Open a page you already have and TidyTabs asks which copy to keep. A duplicate only closes while an identical tab stays open.
Tab budget
Give each window a cap. Tabs over it park in a restorable list and come back on their own as room opens.
Auto-close
Pick an idle limit and tabs past it close on the next sweep. Sites you exclude are left alone.
Keep
Right-click a page to keep tabs on it. It won't be auto-closed or parked, and it stays reopenable after the tab is gone.
Tabs that are active, pinned, playing audio, kept, or in a tab group are never touched. When TidyTabs closes a tab, it waits in history for as long as you choose, up to 90 days, one click from coming back.
