How can I get rid of the white stripes at the top of the screen that covers navagation bar?

When I opened Firefix, there is a (sometimes blue) white stripe at the top of the screen that hides the navigation bar. I can't intervene except search because I can't click on the arrow invisible return, bookmarks, reduce or close the screen. I have to close the browser by right click on the Firefox icon in the task bar and click Close.

First of all, could check you that Firefox is not full screen mode: by pressing the F11 key usually toggle between normal view and full screen. In addition, full screen, drag the pointer of the mouse to the top must cause the toolbar area to slide down. Then you can right click on an empty area of the tab bar (or the button '+' on the tab bar) and choose the output runs full screen in the context menu.

Could test you mode without failure of Firefox? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules - try pressing Alt + h and then the letter r to trigger this command

and OK reboot.

Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

Any improvement?
