Blank space above address bar in full screen mode on Mac

Hi. Blank space appears above address bar in full screen mode when I bookmark specific web page for the first time after FF start. Only way to hide this space is View->Toolbars->Customize->Done. But it appears each time after FF restarts. Disabling all addons does not help. This problem disappears only in FF safe mode.

Thanks, Roman

Didn't help. Same problem after FF restart.

Forgot to mention that this problem appears only in full screen mode.

Disable all extensions and If the problem no longer occurs, one of your extensions was causing it, then re-enable each extension one at a time to check it.

thanks again

Didn't work. It was the first thing I did.

you write that you disable add-ons, you disable extensions as well ?

I disabled everything in Extensions and Plugins tabs.

Switch to the default theme then because in safe mode the default theme is used, without a persona.
