Open Firefox, test server, file transfer failed

Firefox, test server, file transfer failed

there is an error prompt on top ".....data transfer full...." i can't remember it exactly

I suggest the following features:
Dragging a file to the device i want to send
after i release the mouse button.
there will be a progress bar (In both device), telling me is it uploading/downloading or what.

Many thanks.

 

Still failed (for 5 months),
I tried press the "send files to your devices" it give me a little green colored prompt on lower right hand corner of my Firefox in PC. It said "sent sucess". But nothing pop up from the android phone..


###edit###

Oh i figured it out. The doc file will send to the path
Picture will send to the path DCIM/Join in my phone
while the doc, txt ,zip file will be sent to the /Join/Files

Can we edit the path for receiving files?
Also, it only works for me if i drag and drop the file to the firefox browser, but not for clicking the "send files to your devices" button.

Please check if i was wrong.
