In the new Firefox update, tab and toolbar icons have increased in size. The tick box to use small icons is no longer working. Is there something I can do to fix this ?


Thank you

Chosen solution

hello, firefox 22 is now respecting the pixel density you've set on a system level in the windows control panel > appearance > display. more information about that is availbale at http://windows.microsoft.com/en-us/windows7/make-the-text-on-your-screen-larger-or-smaller

if you want to set the text size/pixel density in firefox different from that of your system's settings like it was handled in prior versions, enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named layout.css.devPixelsPerPx. double-click it and change its value to 1.0 (or any other zoom factor that fits your purpose; -1.0 is the default value and will adhere to the system settings).

Thank you for your help.

I have set layout.css.devPixelsPerPx to 1.4, toolbar icons remain large.

This also changes firefox's font size and reducing css.devPixelsPerPx can make text unreadable.

Code changes regarding HiDPI support have landed in Firefox 22 and later (bug #844604).

You can modify the layout.css.devPixelsPerPx and increase or decrease the value in 0.1 or 0.05 steps to adjust the size of fonts and other elements in Firefox.

  • The layout.css.devPixelsPerPx pref is a String value parsed to a float and allows to fine tune the dimensions of all elements (user interface and web pages) more precisely (resolution 0.1 or 0.05).
  • Change the default value -1 to 1 to make it work like in previous Firefox versions (100%)
  • Use values between 0.05 and 1.0 to reduce elements in size.
  • Use values greater than 1.0 to magnify and make elements larger (percentage divided by DPI, % / DPI).
  • http://kb.mozillazine.org/about:config

If web pages needs to be adjusted after changing this pref then you can look at the Default FullZoom Level or NoSquint extension.

Use this extension to adjust the font size for the user interface:
