I have a HiDPI screen and use Ubuntu 18.04 with KDE Plasma. While applications with title bars (including Firefox) have scaled title bar button icons, when I disable it for Firefox ,from customization page, these icons stop being scaled. In the image you can the difference between the sizes of icons.

Hi hu1997tr, What theme are you using? Try the default Dark theme and see if the problem still occurs.

Does it make a difference if you have the menu bar visible?

Firefox has three possible places for the window controls: title bar, menu bar, and tab bar) and the size can depend on on what toolbar the controls are displayed.

Thanks for your answers. For the first answer, I am using the default dark theme. But I also realized thanks to you that icons are always white which makes them nearly invisible with light themes. For the second answer, this occurs in tab bar controls. I use Firefox this way for better screen use, my device has a pretty small screen size of 13 inches.
