Laptop:
Notice how the Desktop image has no titlebar above the tab and the Laptop image does have a titlebar above the tab? Why?
I confirmed both versions of Firefox are exactly the same and have the same theme and no extensions. Is this difference a result of some about:config setting or something? I would like for the Laptop version to NOT have a titlebar.
Click on Firefox's ☰ icon on Top-Right,
Then the Customize... option.
On Bottom-Left, Uncheck "Title Bar".
Done!
Alternatively,
Click on View Menu Option,
Then Hover over Toolbars to show more items,
Click on Customize... option.
