The font at the top of the page (search bar etc) is way too small for me to read comfortably. How to enlarge it?

Can you attach a screenshot?


You can set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page. Adjust its value in 0.1 or 0.05 steps (1.1 to enlarge or 0.9 to reduce) until icons or text looks right. Make sure not to use values too large or too small.

  • modifying layout.css.devPixelsPerPx affects user interface and webpages (global zoom)

Firefox has a Zoom section in Settings to set the default zoom level for webpages.

  • Settings -> General -> Language and Appearance -> Zoom

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
