Every JS plugin is assigned a unique ID. When an instance of a JS plugin is created the frame loader that we use to load the plugin's handler URI will create a special TabContext. This TabContext causes the ContentParent to use the process for this specific JS plugin (creating one if it hasn't already) when it creates the PBrowser actors. This causes the iframes for all the instances of a specific JS plugin to be grouped in the same process. --HG-- extra : rebase_source : c39560bdf66cda1a005c7b823b3a46e4734878a4 extra : source : 9cba1db527c7eed4371c9f4caf96fd942608cab6
