Aesthetic issue on mobile

[Alessio Ciregia]

Hello.
First of all: congratulations, great work.
Then I'm not sure if this is the right place to report issues. Is it
supposed to use bugzilla? Or pagure?
Maybe you are already aware, but I would like to report that on an Android
phone, using Firefox or the stock browser as well, in the right side of the
header there is an hamburger menu icon that seems useless. This icon is not
present using Firefox on a desktop PC.

Ciao,
A.
