On Window 11 Pro using Firefox on a 15.6 laptop computer I would like to reduce/minimize the size of the taskbar etc etc at the top of the page. I assume a setting in about:config would be the way to go, but which one? Any suggestions most gratefully accepted.

AskWoody MVPJanuary 12, 2025 at 2:42 pm #2736903To reduce the width of the firefox browser menubar
Within about:config search for: browser.compactmode.showIf not there, you will need to create a ‘new boolean’ called:
browser.compactmode.show
set the value to TRUE
Exit about:configClick on Hamburger on top right corner within firefox
Navigate to More Tools > Customise Toolbar.
Select the Density dropdown button at the foot of the presented page
then select Compact (not suppoted)
Which reduces the height of the menubar.
Default is NORMALI’ve been using this for years without issue, even though it states (not supported)

AskWoody MVPJanuary 14, 2025 at 3:46 pm #2739518You can also use this pref in about:config:
layout.css.devPixelsPerPx
The default is -1, which is the same as 1 (100%).
Positive numbers smaller than 1 will shrink the UI. Numbers larger than 1 will enlarge it.
set it to 0.85, for example, if you want the UI scaled to be 85% of the default size.
This should work fine in Windows and Linux if you are using X11. It has not worked in Linux under Wayland in Waterfox! I have no idea if it works on Macs.
