In firefox, when I try to export my bookmarks as html, it only exports the bookmarks toolbar no matter what I select.

When I try to import a json full backup, the app says "he file submitted for this source should be html" (note the typo)

I looked at some old code of mine and it seems like I had to implement JSON for ff imports.

Sorry, it's a ruby code snippet haha:

   def load(content)
     @json = JSON.parse(content)
   end

   def check_element(el)
     if el['type'] == 'text/x-moz-place'
       @bookmarks.push({
         title: el['title'],
         url: el['uri']
       })
     end
     (el['children'] || []).each {|c| self.check_element(c) }
   end
   def get_bookmarks()
     self.check_element(@json)

     return @bookmarks
         bmark = {}
         bmark[:url] = child.attribute('href').value
         bmark[:title] = child.inner_text
         @bookmarks.push bmark
   end
