Hi Nikilet

Could you please start a new thread for your question?

Then you can provide more information like your operating system and installed add-ons.


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 or 0.9) until icons or text looks right. Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom). You can use an extension to correct the appearance of web pages.

You can look at Zoom Page WE and NoSquint Plus extension to set a default font size and page zoom on web pages.


You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
