Bookmark Doctor – Duplicates & Dead Links EN

Fix years of bookmark clutter, safely.

Years of bookmarking leave duplicates, dead links, folders with nothing inside and entries with no name. Bookmark Doctor finds all of it in seconds and proposes a clean-up - but it never touches a bookmark on its own.

Every change goes through a review list you can untick, and a complete backup is saved first, both inside the extension and as a standard bookmarks file you can import into any browser. If you change your mind, restore the backup into a new folder.

An optional link check visits each bookmarked address once, without your cookies, to find pages that are gone or have moved to a new address. Your bookmarks never leave your browser.

KEY FEATURES
• Exact duplicates, HTTP/HTTPS copies and near duplicates (www, trailing slash, #section, tracking parameters)
• Keeps the best copy automatically: https, titled, nearest the bookmarks bar, oldest
• Empty folders (including nested empty folders)
• Missing titles with an editable suggestion
• Dead and moved links (optional check, without cookies) with status codes and new addresses
• Look-alike domains, raw IP addresses, insecure sign-in pages, bookmarklets and data: URLs flagged for a look
• Folder suggestions for loose bookmarks from the same site
• Nothing changes automatically: review every change, untick anything, then confirm
• Full backup before every change - saved in the extension and downloaded as a standard bookmarks HTML file
• Restore any backup into a new folder without deleting anything

PRIVACY
Your bookmarks are analysed in this browser and never uploaded. Changes happen only after you review and confirm them, and a backup is saved first.

GOOD TO KNOW
• Some sites refuse automated checks or need sign-in; they are shown as "needs sign-in or blocks checks", not as dead.
• Server errors (5xx) and timeouts can be temporary, so they are never proposed for removal.
• Restoring a backup adds its bookmarks into a new folder; it does not replace your current bookmarks.
• Browsers do not let extensions edit the managed bookmarks set by an organisation.
