Bookmark Sentry

Bookmark Sentry is a lite add-on for Google Chrome that allows you to find and eliminate duplicate entries and broken links in your bookmarks and favorites.

IT just takes a few seconds to scan all favorites and it will tell you if there is something wrong.

Bookmark Sentry can be really useful, because sometimes those favorites are stored there for a long time and those websites disappear and the list of bookmarks is so long you don't find what you need. By this way you will be sure that all those links are necessary and are working properly.
