Systems and methods are described that include receiving, in a tab strip generated by a web browser application, a request to generate a tab group, generating the tab group, in response to receiving the request, where the generating includes generating a tab group identifier for the tab group, enabling pausing or starting of an activity associated with a resource accessed by a browser tab within the tab group based on whether the tab group is collapsed or expanded, and storing metadata about the tab group and the browser tab included in the tab group. The systems and methods may further include causing display of the generated tab group in the tab strip with the tab group identifier depicted in at least a portion of a user interface associated with the browser tab where the generated tab group is configured for display based on the metadata.
