Same approach as the other bug, mostly replacing automatically by removing 'using mozilla::Forward;' and then: s/mozilla::Forward/std::forward/ s/Forward</std::forward</ The only file that required manual fixup was TestTreeTraversal.cpp, which had a class called TestNodeForward with template parameters :) MozReview-Commit-ID: A88qFG5AccP
