Bookmark Backup is a simple extension that helps to keep your bookmarks (and optionally other Firefox settings) safe. Each time Firefox is closed, a copy of your bookmarks file will be made to a backup location. If Firefox's bookmarks become corrupted or lost, find the most recent uncorrupted backup and copy it into your profile folder.
Changes in version 0.3.1:
* The most common settings now have a checkbox in the Options dialog to make it easier to specify the files to be backed up.
* Each day's backups are now copied into a sub-folder of the Backups folder, this keeps the files for each day together and resolves the problem of files getting the wrong extension.
* Removed the automatic install.rdf update link due to bandwidth constraints, from now on you'll have to manually check for updates.
