TabKeeper

You won't open most of these again.

It closes tabs you've forgotten about, warns you first, and never touches anything you're actually using.

What it does

That's the full list — nothing else runs in the background.

Configurable threshold

30 minutes to 7 days, or set your own. Checked once a minute in the background.

Always protected

Pinned tabs, your active tab, anything playing audio or on a call, browser pages, and whitelisted sites are never touched.

Domain whitelist

Add any domain that should never close — gmail.com, your docs, whatever you rely on. Saves instantly.

Cancellable warning

Before anything closes, a notification tells you what's about to happen — with time to cancel it entirely.

Recently closed

Every closed tab is saved with its title, favicon, and URL. Restore one, restore all, or clear the list.

Pause anytime

Pause for 15 minutes, an hour, the rest of today, or until you turn it back on.

Safety

What never gets closed

Six checks, every time, before a single tab closes.

How it works

Three checks, every minute

It checks your tabs once a minute using a browser alarm — no background page, no polling loop.

1

It watches focus, not history

It records the last time you clicked into a tab — not what's on it, not your browsing history.

2

Past the threshold, you get a warning

A notification says how many tabs are about to close. Cancel it, or it goes ahead.

3

Restore anything, anytime

Every closed tab is saved with its favicon and title — one click puts it back where it was.

That's the whole thing.

Install it, pick a threshold, and stop thinking about your tabs.
