Bookmark folders duplicated after upgrade

I have noticed over the years that when I upgrade to a new Firefox, the bookmark folders are duplicated. If I sort, there are now 3 sorted sets of bookmark folders under bookmark menu. In the early days, I took hours and manually merged or deleted individual items. Briefly I had an add on that eliminated duplicates but I believe it was incompatible with ff 5 or 6. Any current quick solution to eliminate duplicate folders and merge bookmarks?

Check your about:config the following (also check that you have nothing for that variable in user.js, if and only if, you have a user.js):

Browser.places.importBookmarksHTML When migrating from a version that uses a flat file to store bookmarks, this preference determines whether the old bookmarks are imported.

  • False: Do not import the contents of bookmarks.html. (Default)

You should not be responding to any message to import bookmarks, since you are still using the same profile with an update.

You should be deleting the unwanted folder of bookmarks rather than haphazardly having "Duplicate Bookmark Remover" remove a duplicate from one folder or another -- see "CheckPlaces" extension for something current. The unwanted folder is likely to be at the bottom of the "Bookmarks Menu" looking in the bookmarks sidebar, or in the bookmarks library list.

Don't forget that you do have bookmark backups for 5 days for which there was actual usage in a day, and you might want to increase the number of backups to the new default of 10.
