This will show you how to delete duplicate and stale old bookmarks in chrome. The extension checks each of your bookmark links and if the page responds, the bookmark is kept, if the bookmark returns a 404, or not-found error, then the bookmark is removed!

bookmark sentry is the extension that I’m going to use for the task.

click on the link above and install the extension.

• goto spanner [wrench]
• goto tools > extensions
• find bookmark sentry
• click on options

Delete duplicate and stale old bookmarks in chrome

Bookmark sentry will now start scanning your bookmarks and will tell you of all the problems it finds. You can schedule monthly scans, etc =)
