Firefox quantum not showing donwload progress bar

[Alexandre Speltri]

using ubuntu 18.04 daily build (ubuntu-session gnome) , but the same problem happens when using firefox (57.0.1) quantum under ubuntu 17.10 . When downloading any file , the progress bar (on the dock) over the firefox icon is not showing anymore (an example screenshot has been attached). On the other hand, nautilus file manager still has it's progress bar when copying / pasting files.
