Hello, Make sure that you are in either the Bookmarks Toolbar folder, Bookmarks Menu folder, or Unsorted Bookmarks folder so that you can create a new folder. --------- If you are in any of those folders and still cannot create a new folder, do you also have problems creating new bookmarks? If so it could point to a problem with your ''places.sqlite'' file. Either enter '''about:support''' in your address bar, or go to: * Help (or [[Image: New Fx Menu]] > [[Image: Help-29]]) > Troubleshooting Information Beside Profile Folder, click the "Show Folder" button to access the location of the file. Make sure it isn't read only. You can also install the [https://addons.mozilla.org/firefox/addon/places-maintenance/ Places Maintenance] extension to run maintenance on the file. Please read the following articles first as they provide helpful hints and instructions that may be relevant to you: * http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox * https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file
