This article deals with problems adding, deleting, and making changes to bookmarks. For bookmarks that were saved previously but are now gone, see lost bookmarks.

Changes lost on restart

This problem can be caused if the bookmarks.html or bookmarks.html.moztmp file in the profile folder is "read-only" (Windows) or "locked" (Mac) . Deleting or modifying bookmarks will also have no effect and the profile folder will fill up with multiple "bookmarks-<n>.html files, where <n> is a number. Removing the "read-only" attribute or unlocking the file will again allow the bookmarks to be updated (bug 157152). To do so on Windows systems:

1. Navigate to the profile folder
2. Find bookmarks.html and (if it exists) bookmarks.html.moztmp
3. Right-click on the file, choose Properties
4. On the General tab, make sure "Read only" is not checked.
5. Press OK.

See Multiple profile files created for additional information.

Bookmark Duplicate Detector

The Bookmark Duplicate Detector extension may cause the Add Bookmark dialog to fail [1]. If updating the extension doesn't help you should uninstall it.
