Bug 329750 moved "Clear Private Data..." from the Tools menu to the History menu. Oh, and the "Go" menu has been renamed to "History" (Places only). There are also a couple of new items in the History menu, "Search in History" and "View All History", but the final UI isn't done yet.

> Oh, and the "Go" menu has been renamed to "History" (Places only). Some of the changes for this were done in Bug 336058. I'm not sure if there's more to do for that particular item. Also this isn't places only anymore.
Bug 336058 did indeed change the docs as well, although it didn't rename the anchors. We'll file new bugs once there are further changes on the branch (like moving Clear Private Data to the History menu). The Places UI on the trunk is far from being in a final state, and not actively worked on for a couple of weeks, so don't bother about it now. *** This bug has been marked as a duplicate of 336058 ***
