Export bookmarks
From MozillaZine Knowledge Base
You can save a copy of your bookmarks to an HTML file, using the Export feature of the Bookmarks Manager:
- Mozilla Suite/SeaMonkey: "Bookmarks -> Manage Bookmarks... -> Tools -> Export..."
- Firefox 2 and below:: "Bookmarks -> Organize (or Manage) Bookmarks... -> File -> Export..."
- Firefox 3: "Bookmarks -> Organize Bookmarks -> Import and Backup -> Export HTML..." (This will save a bookmarks file in HTML format, which can be imported by other browsers. To save a bookmarks file in JSON format which can only be restored in Firefox 3, use "Import and Backup -> Backup..." )
Note: If exporting bookmarks to an HTML file does not work in Firefox 3, see Unable to export bookmarks to HTML file - Firefox
An exported bookmarks file can be saved for backup, in case of future problems with your bookmarks (see Lost bookmarks - Restoring bookmarks from backup). You can also transfer bookmarks saved in HTML format to another Mozilla application or profile using the Import from file feature of the Bookmarks Manager.
