CheckPlaces

CheckPlaces is a simple extension for Mozilla Firefox that allows you to check if your favorites keep functioning correctly, if you don't have duplicates or if there's an empty folder.

Using it is as simple as clicking on its icons, situated in the lower right corner of the browser window, and selecting the option 'check'. In a few seconds, the program will finish the analysis showing you the corresponding results.

The decision about what to do with the duplicates or if they stopped working will stay at the discretion of the user, so if you want to look for a substitute web page for one that stopped working, you can do it before deleting the broken link.

CheckPlaces is a very interesting extension for those users with dozens and dozens of favorites, or those who, because of Firefox Sync (or similar applications), have a lot of duplicated favorites.
