Recently Mozilla released its newest version of Firefox which is great but I ran into a bug.

The default settings have Firefox take over the title bar which can cause some issues.  In the computer I looked at, the Window would not auto-resize when you dragged it to the edge of the screen (a feature in Windows 10)

Title Bar Example

[The area where the title of the window and the “X” button is located is referred to as the Title Bar]

If you want to change the setting you will need to right click on the title bar and click Customize.  Then on the bottom of the Customize Screen there is a checkbox for Title Bar.  Make sure that is checked off and the Windows Title Bar will reappear and functionality will be restored.

Final Thoughts

I’m not 100% sure what triggers the bug, I tried it on my own Windows 10 machine and the bug didn’t present itself.  However, I know of multiple machines that this has happened to.  You can download the new browser here
