How can the size of the icons, buttons, and toolbar bookmark fonts be adjusted to be bigger? They are tiny and I would like to have control over this but it seems like there is no way to do that, only within the pages.

I am using the latest firefox on a mac w/ catalina.

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. you might need large value above 1.5 or 2.0.

  • 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. If you get the warning page, you can click the "Accept the Risk and Continue" button.

WARNING: modifying prefs directly via the about:config page can sometimes break Firefox or cause strange behavior, and there is no guarantee that this will keep working in future Firefox releases, so be cautious with modifying prefs if you aren't sure you understand their purpose. You should only do this if you know what you're doing.
