Tab Wrangler vs Tabs Outliner

Tab Wrangler is a free browser extension that closes tabs after a period of inactivity, with a one-hour default timeout. Closed tabs are kept in Tab Corral, a searchable, sortable list where they can be restored with one click. Some restorations retain browsing history and scroll position, subject to the browser’s limit of the 25 most recently closed tabs. Users can lock tabs or windows and automatically protect tabs from specified sites. Audio-playing and grouped tabs can also be protected as options, while pinned and active tabs are always protected. Settings include a minimum number of open tabs before automatic closing starts, a pause control, keyboard shortcuts, and import or export for saved tabs and settings. The extension is available for Chrome and Firefox. Browser-account sync can carry settings if enabled, but closed tabs are stored locally and are not synced. The developer says the extension sends no user or usage data and has no tracking, analytics, or advertisements. It can read tab titles and URLs, but not page contents. Saved-tab capacity depends on the browser’s storage quota.
