Overview
Puts idle tabs to sleep after 15 minutes by default. You can change the time.
WHAT IT DOES Tab Drowse unloads inactive tabs to save memory, using the browser's built-in tab discard. By default, a tab becomes eligible after 15 minutes without being opened or reloaded. Choose 1, 5, 10, 15 or 30 minutes, or 1 or 2 hours in the popup. Checks run about once a minute. The tab stays in the tab bar with its address. When you return, the page starts loading again; loading time depends on the site and your connection. HOW IT WORKS This auto tab suspender uses native discard rather than an extension replacement page. A local page check has a 2-second timeout, so an unresponsive page check does not hold up the other tabs. Sleeping tabs get a dashed circle around the site icon and a moon-shaped title marker. The toolbar popup shows the number of discarded web tabs across windows, including tabs discarded by the browser. WHAT IT CHECKS BEFORE SLEEP The extension skips active and pinned tabs, the visible half of a split view, tabs playing sound, and sites on your exception list. It checks for unfinished input, including editors inside iframes and Shadow DOM, detected calls, microphone or camera use, screen sharing, and paused media partway through playback. Sites with notification permission already allowed are also skipped. These checks do not back up drafts or guarantee that every website's unsaved state can be detected. Save important work. Exceptions apply to this extension; the browser's own Memory Saver operates separately. PRIVACY Checks run on your device. To detect unfinished input, the extension reads field values and editable text locally. It checks media state and whether notifications are already allowed; it does not record audio, video or your screen, or request notification permission. Page content is not sent to the developer or an external server. There is no account, analytics service or extension backend. Site exceptions are stored locally, without browser-account sync. The extension does not load remote executable code. HOW TO USE IT Install the extension and continue browsing. Open the toolbar popup on a website and enable the switch to keep that site awake. You can also use the page's right-click menu. Remove a site from the exception list when it no longer needs protection. Exceptions match the exact hostname; subdomains are separate. Localhost and 127.0.0.1 are excluded by default. Use the popup's pause button to stop this extension from putting tabs to sleep for one hour. You can resume early. Pausing does not reload tabs that are already asleep or change the browser's own memory management. This is a memory saver for desktop browsing, not a session backup or a tool that prevents every reload. It does not promise a fixed amount of saved RAM.
