Abstract: Configurations for sharing an instance of an executing process for a plug-in based on a session and a cookie data store associated with the session are disclosed. A cookie data store can be associated with a tab running in a corresponding security mode. By way of example, instead of initiating a new process for the plug-in in a new tab, the subject technology can first determine whether a previous tab is running an instance of a plug-in process. If this is the case, the subject technology can then determine whether the previous tab is running in the same security mode (e.g., protected or unprotected) as the new tab. The subject technology then shares the existing plug-in process in the previous tab without instantiating a new plug-in process in the new tab.

Abstract: A computer-implemented method for comparing multiple client application variations, including, providing a copy of a client application to each of a plurality of client devices, wherein each copy of the client application comprises multiple application variations, receiving demographic information from one or more of the plurality of client devices and providing a list of available experiments to each of the plurality of client devices based on the demographic information, wherein each of the available experiments corresponds with one or more application variations. In certain implementations, the method further includes steps for receiving usage information for each copy of the client application associated with each of the plurality of client devices and comparing two or more application variations of the client application based on the usage information. Systems and computer-readable media are also provided.
