I think you used the Flash widget with Mint because that uploader looks for
available widgets in the following order:
'flash,gears,silverlight,browserplus,html5'.
I found the change I made on my site and I used:
'html5,flash,html4'.
Which explains why it shows the Flash frontend instead of an HTML 5 one.
I tested on a Fedora live CD which does not include Flash and has Firefox 7.
As expected it defaults to the HTML5 widget, but it fails in the same way as
I mentioned before.
I had a look with Mint 11 and the CD I've got has Firefox 4 and no Flash by
default. It used the html5 frontend and I could upload files there by
dragging.
Then I updated Mint 11's Firefox to 8 and it fails in the same way as Fedora
and Trisquel when Flash is disabled.
I get the following error:
A.name is undefined
http://builder.eluaproject.net/web/lib/jquery/plupload/js/plupload.full.min.js
Line 1
across all three distros when I try to upload with Flash disabled.
It seems like something in the newer versions of Firefox (and therefore
abrowser) breaks Plupload in HTML 5 mode. I don't know if eLua is using an
old version of Plupload and if they can do something about this.
