I backed up my bookmarks to an external drive, rebuilt my system, and now when I try to restore from that file, I get "unsupported file type" How can I restore from this file?

Make sure that the backup file with the bookmarks has the correct file extension: .html for a HTML backup and .json for a JSON backup.<br />
You can check that via the right-click context menu of that file and open the Properties.<br />
If you are not sure about the file type then you can open the file in Firefox via "File > Open File"<br />
A JSON backup will show as one long text line without line breaks and a HTML backup as a web page with clickable links.<br />
A JSON backup starts with: {"title":"","id":1,"dateAdded":<br />
An HTML backup starts with: <nowiki><!DOCTYPE NETSCAPE-Bookmark-file-1></nowiki>
You may need to add quotes ("") around the name to rename the file to the correct file extension.
