While we’ve always been a fan of AM Deadlink to check out bookmarks for dupes and errors, CheckPlaces for Firefox is fast becoming one of our favorite utility extensions. CheckPlaces will also look for new favicons.

Ever wanted a customized folder on your Firefox Bookmarks bar that just shows whatever bookmarks that match your search terms?
Open up the bookmark organizer (Ctrl+Shift+B), do a search through your bookmarks, click Save, give it a name, and then drag the new search bar (at the bottom of the Bookmarks Menu) over to the Bookmarks bar (or wherever else you want it).
This tiny app will find and remove dead links and duplicate bookmarks. Lost a favicon? AM-Deadlink will find that too. Works with Firefox, Internet Explorer and Opera.
