Google Chrome will soon let you search through your open web pages to find that missing page lost among a sea of tabs. Google is testing a new ‘Tab Search’ feature in the Chrome Canary builds that allows you to search your open tabs for a particular keyword. This feature is currently being tested in Chrome 89 and will not be available in the Stable versions until March 2021. If you wish to test this feature now, you can download Google Chrome Canary and follow these steps to enable the feature.
