At the moment I'm using ff beta on a Galaxy s4, 4.4.3 operating system. Every tutorial starts by pressing 3 dots on the upper right to reach a menu... There are no dots, no menu, just tabs. I noticed this in Chrome too. Only the "Internet" button has it's ribbon to make a bookmark, everything else I can't even do step one in the tutorial because there is no menu button. Surely ff has some other clever way to make a bookmark or get to the menu? All I can figure out is holding down your finger on the address bar gives options like copy or share, no bookmark. I feel like the biggest idiot a simple bookmark is beyond me...
