Common questions

Will I lose anything when a tab is put to sleep?

No. Sleeping uses the browser's native tab discarding: the tab stays in place with its title and position, and reloads when you click back to it. Its back/forward history is preserved. Unsaved text typed into a form is the one exception — protect those tabs with the shield button.

How do I get a tab back?

Click the tab, or use the ↺ button on its row in the popup. To restore everything at once, use Wake all.

How do I stop a tab from ever sleeping?

Click the shield icon on that tab's row. Pinned tabs and tabs playing audio are already protected by default, and you can change that in Settings.

Are the memory and carbon numbers exact?

No, and the extension says so. Browsers don't expose exact per-tab memory to extensions, so per-tab figures are estimates derived from tab state. The system memory total in the popup footer is measured. Set your region's grid carbon intensity in Settings for a closer carbon figure.

Why did my saved CO₂ go up right after I reset it?

Because tabs that are still asleep keep genuinely saving energy, and EcoTab keeps counting it. Resetting zeroes the score; it doesn't wake anything.

Can I turn automatic sleeping off?

Yes — Settings has a switch for it, plus the idle threshold in minutes. You can keep the measurement features and never auto-sleep anything.

Does it work in Firefox?

Yes. The system-memory gauge is Chrome-only and hides itself on Firefox; everything else works the same.
