In describing the History feature, the documentation says "* To choose from pages you've visited during the past several sessions, open the Tasks menu, choose Tools, then History. You see the history list. The history list displays a list of folders. Double clicking the folders displays subfolders or bookmarks to web pages. You can double-click the URL next to the Bookmark icon to view that page. " At least in the Windows version there is no Tasks menu: you get to History directly from the Tools menu. (I know this is pretty nit-picky, but I actually know someone who came to ask me how to find the History menu, because he read this and couldn't find the Tasks menu.)
Thanks for the feedback---not nitpicky at all! The general problem is that the Mozilla help content lags behind the NS content, so, unfortunately, some of the references to UI items are obsolete/inaccurate in Mozilla. That's REAL BAD. We're taking steps to remedy that. Reassigning to Jatin for any additional comment and to resolve as appropriate.
The online help that will eventually replace the current Mozilla help has already been revised to say: "To choose from pages you've visited during the past several sessions, open the Go menu and choose History...." Ian Oeschger <firstname.lastname@example.org> plans to carpool the revised help as time permits.
problem still exists
