Thank you very much for the information. I thought all was lost. Whew. I do not know if the bookmarks can me moved to work with the "Bookmarks" with drop down in Firefox.

Thank you again.

Check with Google support to find out how to export your Google bookmarks to bookmarks.html format, which is the universal method for transferring bookmarks / favorites from one browser to another. Then you will be able to import that bookmarks.html file into Firefox.

I found them at the top next to Help, titled GBookmarks. I created this thru a link you provided and never could find where it ended up. Duh. Although all the individual bookmarks are not there. Have a good day! Thank you.
