You can easily hide the new Recently Bookmarked section with the five most recently added bookmarks. The others, it depends. '''Recently Bookmarked ''section''''' You can hide the gray heading Recently Bookmarked and following five bookmarks using one of these methods (apparently not all work on Mac): '''(1) Context Menu''' Right-click the "Recently Bookmarked" text and choose Hide Recently Bookmarked from the bottom of the right-click context menu (see attached screenshot) ''Note: A user reported this doesn't work on the Bookmarks Menu on the main menu bar on Mac, only the bookmarks menu that drops from the toolbar button, which is pictured in the screenshot.'' '''(2) Directly Edit a Preference''' The menu item switches a hidden preference from true to false, and you can do that directly as follows: (A) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button promising to be careful. (B) In the search box above the list, type or paste '''book''' and pause while the list is filtered (C) Double-click the '''browser.bookmarks.showRecentlyBookmarked''' preference to switch the value from true to false '''Most Visited smartfolder''' There's no built-in feature to hide/show this search folder. But you could either (A) drag it into a subfolder where it's out of your way but available for future reference, or (B) delete it. Sometimes it is easier to use the Library dialog. Either: * Ctrl+Shift+b * "Show All Bookmarks" To delete the folder, right-click > Delete. '''History?''' As for the larger question of keeping a list of the addresses you've visited, that's your history. So check out these articles: * [[Settings for privacy, browsing history and do-not-track]] * [[Private Browsing - Use Firefox without saving history]]

Thanks - right click & delete took care of it!
