Bookmark Dupes: Firefox Add-on for Bookmark Management

'Bookmark Dupes' is a Firefox add-on that simplifies bookmark management by identifying and removing duplicate bookmarks and empty folders. Designed with a user-friendly interface, it provides options to display duplicate bookmarks, empty folders, or all bookmarks. It also has an Expert Mode for customized rules. Note: It is mandatory to create a backup of bookmarks before using since removing bookmarks or stripping descriptions are irreversible actions.

Add-on summary

After installing bookmarkdupes, the basic usage is rather simple:

To open bookmarkdupes, click the extension symbol (duplicate stars) or use the link in the options page of the extension. Do not enable expert mode (unless you know what you are doing, see separate section). Then select what you want to display:

  1. Bookmark duplicates
  2. Empty folders
  3. Non-duplicate bookmarks</<li>
  4. All bookmarks
After this, you will be offered the list of bookmarks with checkboxes; in case 1 the numbers indicate the order in which matching bookmarks were added according to the internally stored date. There are also button to select/unselect convenient sets of checkboxes. Finally, there appear buttons to remove the selected bookmarks (or to move them to a “Dupes” folder) in cases 1-3, or to strip the descriptions of the selected bookmarks in case 4. (The latter has some side effects, see section Known Bugs).

Be aware that removing/moving bookmarks or stripping descriptions is irreversible! It is recommended to make backups of your bookmarks first!

Currently, there is no working version available for android (see section Known Bugs).
