Similarly to nsITabParent, TabChild is exposed to frontend code via nsITabChild. It's not clear what the future of this interface will be, but for now we can just rename it to nsIBrowserChild. Differential Revision: https://phabricator.services.mozilla.com/D28134 --HG-- rename : dom/interfaces/base/nsITabChild.idl => dom/interfaces/base/nsIBrowserChild.idl extra : rebase_source : a6c42a661e35b19e46c60f6f6a6f3dab64c0a1bc extra : histedit_source : 1eb475bd840bf37a3f86294685c9b3c250684e79
