You posted this thread in the wrong place as it is the Firefox for iOS (for iPhone/iPad) section.
In future use https://support.mozilla.org/en-US/questions/new/desktop https://support.mozilla.org/en-US/questions/new/desktop/form in order to post your threads about (desktop) Firefox on Windows.
I moved the thread to desktop.
