When you are logged out and try clicking on the edit or watchlist buttons in Firefox, nothing happens. No alert, no error, nothing. In Safari it tells you that you have to log in. This is in Beta mode.
Juliusz already got this https://gerrit.wikimedia.org/r/71855 Basically there was no position fixed support for Firefox. If you click it you can see the scrollbar height changes. The element was being shown but off the page. Now this seems to work.
