How do I change the menu size in firefox on Linux machine as it is so big unlike on Windows?

more options

i am using firefox on a Linux debian based distro, I am facing difficulties changing the size of the menu e.g width, height and font. I have tried to play with the about:conf > layout.css.devPixelsPerPx value but that did not change a lot for the menu size. so please tell how can I fix this (I am trying to make it smaller) note it is same case when I use firefox-esr for linux as well.

I cannot thank you enough, yes finally I managed to fix the issue by creating a css file in the Firefox profile folder and adding css code that changes the font size for the whole Firefox application on Linux and here is the code I added below: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

  • {

font-size: 9pt !important }


Note:the default was 16pt and for the best one was 9 so it depends and if anyone sees this follow the solution provided by orionnebula141 and hopefully it will get resolved as mine.

problem resolved for me Thanks again
