I tried to customize but the only fonts that I could customize had to do with website content and not Firefox headings, and other lighter and/or smaller print in task bars, menus and other areas. Thank you

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.


You can set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 or on Windows 8 to 1.25 and if necessary adjust layout.css.devPixelsPerPx starting from 1.0 in 0.1 or 0.05 steps (1.1 or 0.9) to make icons show correctly.

Use an extension to adjust the text size in the user interface and the page zoom in the browser window.

You can look at this extension to adjust the font size for the user interface.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.

Thank you for the help. I used the "about:config" fix and it worked great.
