Most Firefox users make use of the bookmarking feature of the web browser to store interesting or important websites so that they can be visited at a later time again. Many of them do add bookmarks regularly while only a few delete unneeded bookmarks regularly which has the effect that the bookmarks folder grow with time. It also means that bookmarks that are no longer needed are still stored in the bookmark's database file.
The Bookmarks Archiver add-on has been created as a semi-automatic option to delete or archive bookmarks that have not been visited for a certain time. The default days are set to 90 but it is possible to change that figure according to the specific needs of the individual user.
The add-on will show a prompt when the first bookmark expires that allows the user to archive or delete the bookmark. Archived bookmarks will be moved into the Archived folder that is created by the add-on automatically. It is furthermore possible to make the add-on perform the archiving or deletion automatically from then on. A click on cancel will leave the bookmark unchanged.
The add-on will automatically run on Firefox shutdown.
Bookmarks Archiver currently has a few limitations that prevent the add-on from working properly in some cases. The History function in Firefox needs to be enabled for the add-on to work at all. Visits to bookmarks will not be recognized by the add-on if the user is surfing in private mode. Finally only bookmarks that are stored in the root folder or in level 1 folders can be archived and bookmarks that are created in the Organize Bookmarks menu need to be visited once before they are being tracked by the add-on.
