I see exactly the same problem when trying to install an extension developed in our research project (http://www.hiit.fi/g/reknow/software/dime_webextension-0.42-an+fx.xpi). It works fine with the mozilla.org version of Firefox (I tested both 49.0 and 49.0.2).

The download starts but the process freezes on the "Downloading and verifying addon" step (even on a clean profile and/or a clean install). In the browser console I get the following error : A promise chain failed to handle a rejection. Did you forget to '.catch', or did you forget to 'return'?
