My iMac menu bar disappears after clicking on Firefox browser. Can anyone help me with this?

One of the screenshots reflects the browser without the menu bar and a light blue strip in its place. Also, I am able to raise the browser over the blue strip. When the menu bar is active, the browser butts up against the bottom of the menu bar.

Safari nor Google Chrome have this issue, only Firefox.

Please help.

Thanks, Cor-el,

I disabled "Grammarly for Firefox" and the issue was resolved; I installed Grammarly in the past few days.

Fortunately, I didn't have restart in SafeMode.

Thanks again!

Make sure you do not run Firefox in Full Screen mode (Mac: Command+Shift+F).

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can use one of these to set which toolbars to show.

  • "3-bar" menu button -> Customize -> Show/Hide Toolbars
  • View -> Toolbars
    You can tap the Alt key or press F10 to show the Menu Bar
  • Right-click empty toolbar area
