How can I increase the font size in the FF57 toolbars and menus

more options

How can I increase the font size in the FF57 toolbars and menus but without affecting content area (displayed web pages). Fonts in toolbars and menus of FF57 are way too small for me.

Using layout.css.devPixelsPerPx 1.25 isn't sulution for me as it also increases font size in displayed web pages. I want to change only font size in FF toolbars and menus.

In previous versions of FF I used Theme Font & Size Changer Addon but in FF57 it isn't able to change font size.

Is it so hard for Mozilla developers to add separate font size changing feature ONLY for toolbars and menus?!

Chosen solution

Wow, this is a very detailed look at Windows settings! What Firefox offers is the following:

Global Zoom Factor

This will enlarge both the toolbar area and the content area:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button accepting the risk.

(2) In the filter box, type or paste pix and pause while the list is filtered

(3) Double-click layout.css.devPixelsPerPx and change its value to 1.25 and click OK, which corresponds to 125% font size in Windows display settings. The toolbar area should enlarge after a few moments. Too small? Try 1.5 and see whether that suits you better. And so on. If you are on Mac and use a Retina display, anything below 2.0 may be smaller than what you started with, so start with 2.0.

Important: Do not go below 1.0 because it may become too tiny to edit.

Websites Too Big?

You can counteract the global zoom with an extension that allows you to reduce zoom on all pages as you open them. You can still fine-tune the zoom level on sites, but this will normalize them.

For example:

https://addons.mozilla.org/firefox/addon/zoom-page-we/

It's a little difficult to find its global default setting for websites, but you can counteract the global setting, for example:

  • Global setting 1.25 + Zoom Page default 80% => pages at 100%
  • Global setting 1.5 + Zoom Page default 75% => pages at 100%
  • Global setting 2.0 + Zoom Page default 50% => pages at 100%

I'm attaching an old screenshot, I don't know if this is still where you set the percentage.

Use this in FF 57: layout.css.devPixelsPerPx and change its value to 1.25 Then in FF 57: Tools / Options / General / Language & Appearance / Fonts & Colors - Advanced button . . . and set web page font sizes there

It works for fonts but not for rest of elements displayed in Firefox window so you will get web pages looking different way than these were created.

layout.css.devPixelsPerPx set to 1.25 affects all elements like fonts, icons, images, ... Tools/Options/Fonts/fontsize is changing font size ONLY. So solution provided above by jscher2000 is better.

OMG, you just saved me from immense frustration trying to configure my new Win10 box, an OS from which MS has taken ALL user font size options away, the $&$^ idiots! Do they think we all have the vision of kids?!? What's the point of getting an HDMI 16:9 monitor when the only option to actually be able to see such tiny text is to reduce the resolution or magnify by 125% (no 110% or 115%, WTF?), which negates the entire point of buying a large monitor?

Question: would this Firefox layout.css.devPixelsPerPx trick possibly work in some manner by modifying the Win10 registry in a similar fashion, if such a string exists? I've installed the WinAero tweaker, but that didn't work for many of Win10's fonts, like the start menu - my neck is getting sore sticking my face in front of the monitor to read that tiny type!

For the Start Menu, try . . . http://www.classicshell.net/

Menu Look / Small icon size - 16, 20, 24 . . . use 24 . . . these are within Programs

Menu Look / Large icon size - 32, 40, 48 . . . 48 makes it go too high, use 32

Skin / [check] Large font

Found the answer - yes, you can tweak the registry to increase font sizes:

https://www.tenforums.com/tutorials/5990-change-dpi-scaling-level-displays-windows-10-a.html

Start at option four down the page, and pay critical attention to "Win8DpiScaling DWORD" - if you don't add and change this, the other settings won't work. And when you change value for LogPixels, type in "78", that will be 120% (decimal default value is 60).

All the questions and answers predate the update to Firefox57. Theme & Font Changer is incompatible with this update. Nothing works to enlarge font for Firefox menus and toolbars.

Firefox: PLEASE fix this. I can't read your teeeny fonts!

Thank you.
