Does Firefox support folder upload?

I enjoy folder upload in Google Drive, which works in Google Chrome.

Recently, I've switched back to Firefox, and when I tried to upload a folder to Google Drive just now:

Google lying about Firefox support of folder upload

Is that true? Does Firefox in fact lack some Folder upload functionality that Chrome has? Or is this a generous wording of Google's decision not to implement the feature for Firefox?


Solution 1:

Current Nightly (version 45) implements Directory upload specification. It can be enabled in about:config using key dom.input.dirpicker.

  • API introduction
  • Firefox bug

Solution 2:

Unless folder uploading becomes a web standard I doubt whether Firefox will implement it.
