If you remember a page but not its browser window, search the browser’s tab collection before scanning macOS windows. A system window list usually sees the browser window and its current title, not every background tab inside it.
Search live tabs first
In Chrome, open Tab Search from the tab strip and type a distinctive word from the page title or site. Google documents that the result list searches open tabs and lets you select the matching tab. Search by domain when many pages use similar titles, and check the browser profile if the expected result is absent.
In Safari, use the tab overview or sidebar search for the relevant window or Tab Group. Search within the correct profile because Safari Tab Groups and browsing history are separated by profile.
Distinguish open, closed, and remote pages
If the page does not appear among open tabs, check Recently Closed and browser history. Chrome also supports searching history by keyword. A history result is evidence that you visited the page, not that its prior form state, scroll position, or unsaved work still exists.
When two results have the same title, compare the domain, surrounding group, profile, and a unique phrase before choosing. Rename the browser window or group afterward if this confusion recurs.
Search at the correct layer
Use a Mac window switcher when you know the active page title or browser window. Use browser tab search when the missing page may be in the background. Wallo organizes browser windows and cannot index every tab, so it should not replace the browser’s own tab search.
