Bookmarks not saved
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 files in the profile folder are "read-only" (Windows) or "locked" (MacOS) . Deleting or modifying bookmarks will also have no effect and the profile folder will fill up with multiple numbered bookmarks-n.html files. Removing the Windows "read-only" attribute or unlocking the file on MacOS will again allow the bookmarks to be updated (bug 157152). To do so on Windows systems:
- Navigate to the profile folder
- Find bookmarks.html and (if it exists) bookmarks.html.moztmp
- Right-click on the file, choose Properties
- On the General tab, make sure "Read only" is not checked.
- Press OK.

Corrupt localstore.rdf
A corrupt localstore.rdf file in your profile folder can cause this problem. To fix it, see this article.
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.
