Importing Firefox bookmarks does not work

The solution below (from Jim) worked. Only the dates were not preserved.

Firefox bookmarks do not appear

This is an issue with how Firefox stores its bookmarks. But there is a setting that will export Bookmarks to an HTML file when Firefox quits. In Firefox, type about:config in the address bar. Click the button to accept the risk. Search for Bookmark Double-click the line that reads Browser.bookmarks.autoExportHTML. The value should be set to True. Quit Firefox. (I actually suggest relaunching and quitting it again, just to make sure.) Attempt the import of Bookmarks into DEVONthink.
