Hello, when I open the Firefox browser from my taskbar it does not open as a full browser page as Image 3.

I have to click on the full-screen icon twice to get it open in full screen as in Image 4.

Please can you help?

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
