Hi

Same behavior for me.
Chrome (60.0) and IE (11.0.9600) are fine.

Objet : [galaxy-dev] Firefox drag and drop not working

Hi all,

we recently updated to our galaxy server and now we would like to use the new feature drag and drop items from the history. It does not work with Firefox but with chrome. In Firefox it says:
The address isn’t valid

The URL is not valid and cannot be loaded.

    Web addresses are usually written like http://www.example.com/
    Make sure that you’re using forward slashes (i.e. /).

Is there anything to enable, install, or set inside Firefox?

Cheers Jochen
