Is the user interface also small? If so, you could try increasing the global scaling factor: (1) Open a new tab to '''about:config''' (type about:config in the Awesomebar and tap the go arrow or tap Enter). ''You may want to bookmark this for easier future access.'' (2) In the search box, type '''devp''' and pause while Firefox filters the list (3) Tap the '''layout.css.devPixelsPerPx''' twice, and edit the value from -1.0 to '''4''' and tap the Enter/Return key. Everything should be significantly larger now. You can edit it to another value, but I wouldn't go below 2 unless you are restoring the default value of -1.0 (tap the Reset button for that). Can you find a value that works?
