Title Bar visibility setting not working on Mozilla Firefox 145.0 (64-bit) for Windows

[J876MM]

For some reason the Title Bar setting on Mozilla Firefox 145.0 (64-bit) for Windows is no longer respected.

Even though I click the check box to enable it, close Firefox, and open it again the Title Bar disappears again.

This is a regression from the last stable version and needs to be fixed.

Bug. Instead of clicking the check box to enable it, try pressing F11 twice. If it works, it's not a fix - just easier to do.
