Abstract: 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.

Abstract: A web browser detects a network privacy threat associated with communications for retrieving a resource from a remote system before the resource is retrieved from the remote system. In connection with detecting the network privacy threat, the web browser automatically retrieves personal information associated with a user of the computing device, generates a privacy threat warning comprising a representation of the retrieved personal information, a representation of the remote system, and a representation of a third-party threat positioned in-between the representation of the personal information and the representation of the remote system, and provides the privacy threat warning for display at the computing device before retrieving the resource from the remote system.
