 ///////////////////////////////////////////////////////////////////////////////
 // SiteInstance interface.
 //
 // A SiteInstance is a data structure that is associated with all pages in a
 // given instance of a web site.  Here, a web site is identified by its
 // registered domain name and scheme.  An instance includes all pages
 // that are connected (i.e., either a user or a script navigated from one
 // to the other).  We represent instances using the BrowsingInstance class.
 //
 // In --process-per-tab, one SiteInstance is created for each tab (i.e., in the
-// TabContents constructor), unless the tab is created by script (i.e., in
-// TabContents::CreateNewView).  This corresponds to one process per
+// WebContents constructor), unless the tab is created by script (i.e., in
+// WebContents::CreateNewView).  This corresponds to one process per
 // BrowsingInstance.
 //
 // In process-per-site-instance (the current default process model),
 // SiteInstances are created (1) when the user manually creates a new tab
 // (which also creates a new BrowsingInstance), and (2) when the user navigates
 // across site boundaries (which uses the same BrowsingInstance).  If the user
 // navigates within a site, or opens links in new tabs within a site, the same
 // SiteInstance is used.
 //
 // In --process-per-site, we consolidate all SiteInstances for a given site,
 // throughout the entire browser context.  This ensures that only one process
 // will be dedicated to each site.
 //
-// Each NavigationEntry for a TabContents points to the SiteInstance that
+// Each NavigationEntry for a WebContents points to the SiteInstance that
 // rendered it.  Each RenderViewHost also points to the SiteInstance that it is
 // associated with.  A SiteInstance keeps track of the number of these
 // references and deletes itself when the count goes to zero.  This means that
 // a SiteInstance is only live as long as it is accessible, either from new
 // tabs with no NavigationEntries or in NavigationEntries in the history.
