I have saved a json file from Firefox with my bookmarks. I had to completely delete Firefox from my computer along with its bookmarks. I re-installed Firefox 27. How do I get Firefox to accept/restore my saved json file as its bookmarks?

Make sure that the bookmarks backup file has the correct (lowercase) file extension:

  • .html for a HTML backup
  • .json for a JSON backup

You can check the file type via the right-click context menu of that file and open the Properties.
If you are not sure about the file type then you can open the file in Firefox via "Firefox > New Tab > Open File" or "File > Open File".
A JSON backup will show as one long text line without line breaks and a HTML backup shows as a web page with clickable links. 

A  JSON backup starts with: {"title":"","id":1,"dateAdded":
An HTML backup starts with: <!DOCTYPE NETSCAPE-Bookmark-file-1>

Verify the file type in the Properties via the right-click context menu to make sure that the change has been successful.

Note that Windows hides some file extensions by default. Among them are .html and .ini and .js and .txt, so you may only see the name without file extension. You can see the real file type (file extension) in the Properties of the file via the right-click context menu in Windows Explorer.
