Pale Moon forum

Here is comparison of the status bar of File Explorer to that of Pale Moon. As you can see, the Pale Moon's status bar has some strange 1-px wide darker line of the color somewhat darker than the rest of controls (pointed with a red arrow). The Pale Moon's status bar also 1 px thicker than standard.

Our status bar is not drawn using native controls (although it looks very similar, by design). As a result, you may encounter some minimal differences compared to native controls with some browser themes/system themes.

This isn't a browser bug.

I know, it is created using XUL but if it is designed to look like native controls, this difference looks like a bug.

If it disturbs you to the point of making a deal out of it, then you are welcome to research the cause and provide a patch to fix the perceived bug, and improve Pale Moon -- just make sure it does not influence other operating systems/themes or cause regressions.
