[2.0.0-rc.1] Saving a Blob on Firefox does not work

[boris-petrov]

The title says it pretty much all. On Chrome it works fine, on Firefox it does nothing. The function returns fine but nothing is downloaded. Tested on Firefox 47.0.2 and 62.0.2.

figure it out, apparently you have to dispatch an event, a.click() is insufficient

edit: Fix on the way
