Toolbar text size.

more options

Hi, I am setting up a laptop for my wife to replace her old one. I have installed Firefox and found that although the main body text is the correct size, the text on the toolbars is very small compared to her old one. How can I increase the toolbar font size without altering the main body. Thank you, Andrew

Hi Andrew, is it a Windows computer? Generally speaking, Firefox uses the scaling (previously called Text Size) percentage set at the Windows level, but you can override it.

This is global setting that will affect web content as well, but it's the simplest approach so please try it first and see how it goes.

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

(2) In the search box in the page, type or paste devp and pause while the list is filtered

(3) Take a look at the layout.css.devPixelsPerPx preference. The default value of **-1** means to follow the system scaling. With large monitors, that usually is 100%, and with laptop screens it often is 125%. Microsoft seems to vary it.

We are going to override this value with a specific percentage, written as a ratio. If there is a tragic typo, use the reset button (left-arching arrow) at the right end of the bar to go back to the default.

Double-click the layout.css.devPixelsPerPx preference to display an editing field. Change the value to 1.5 which means 150% and then press Enter or click the blue check mark button to save the change.

After a few moments, Firefox should resize everything. What do you think? Other common steps would be 1.25, 1.33, and 2.0 but in-between sizes can work, too.

Once you find a comfortable number, you're done. This is the new "100%" as far as page zooming is concerned.

Now if web content is much too big everywhere, you can knock it down using the default zoom level setting on the Options page.

Can you offset those two different features in a way that avoids fine-tuning on most pages?
