Bookmarks LinkChecker is a Mozilla add-on that identifies broken or updated links within your bookmarks.
However, for anyone still using Firefox v0.6.8, the extension can still be a useful tool. Once installed, it will work towards detecting any updated, redirected or broken links within your bookmarks list. This is done by adding icons to the bookmarks drop-down menu, making it easy to keep track of the links with just a glance.
It's worth noting that the only requirement for using the Bookmark Link Checker extension is having Firefox. With this feature, users can rest easy knowing their bookmarks are all up to date and functioning properly.
