How to Enable and Use Tab Groups in Google Chrome

Group Tabs example image

Are too many tabs cluttering up your Chrome browser? Google’s working on a solution to help organize all the tabs you have open. The Tab Groups feature provides neat, color-coded labeling for all your tabs. It’s available today behind a flag.

Warning: This feature is behind an experimental flag, which means Google’s developers are still working on it. Like Google Chrome’s Clipboard sharing feature, it may be buggy, or it may change dramatically in the future. It may even be removed in a future update. We tested this feature in Google Chrome 80.
