I noticed that Firefox (latest version 138.0.3, and versions before this) has a problem with all themes. If I install any theme, the browser can no longer "stretch" properly from the top to the bottom of the desktop. There is always about 4-5mm of space between the bottom edge of the browser and the taskbar. It happens every time I open a browser that was previously closed. If I change the theme back to the original Firefox (dark) theme then everything works normally.
Is there any solution for this? Thanks in advance.
