Can's change font in Firefox

lacov

In settings I've found font settings. My default font is DejaVu (Serif, Sans, Mono)

After changing font (type and size) noting is going on. Even after restart. I disabled option to let wep pages set their own font.

The most important thing for me is to have working "Minimal font size".

To sum up. I can change everything in advanced font settings but there is no result on web pages.

Hi

Best is to use the Zoom feature and set a default zoom level that suits you.

Firefox has a Zoom section in Options/Preferences to set the default zoom level for web pages.

  • Options/Preferences -> General -> Language and Appearance -> Zoom

See "Set a default zoom level for all websites":
