Firefox - Opening New Page

My Firefox - 1504 - has started to open new pages in a size somehat smaller than the screen (as well as first page) - the result is I often touch the wrong scrolling bar and the old pages come up.

Correctable but annoying - is there any way to fix this thru 'options' - ? I have not seen the possibility there to choose something like 'open page to full screen'

 

Rob ...

I suspect that you want a full-sized window, rather than a full-screen display, and the problem is not with Firefox, but with Windows, so there are no settings in FF to correct the situation. Instead,

1. Click and hold the FF titlebar with your mouse pointer, and drag the FF window to the top left corner of your screen.

2. Grab the window's lower right corner and drag it to the lower right corner of the screen (it shouldn't go below the Taskbar).

3. While holding down the Ctrl key, close the FF window by clicking on the Close button (the "X ") in the upper right corner.​

When you reopen FF, you should have a full-sized window. (FWIW, this procedure will work with most windows.)

 

Tks - yup - that worked

What's the difference between 'screen' and 'window' - btw - ?

Any idea what would have caused this change that 'windows' were becoming smaller?

 

A full-screen display is just that ... it fills your screen from corner to corner (an example would be a Powerpoint presentation), while a window allows the Taskbar to be seen, so that other programs or applications can be accessed (Firefox and Thunderbird open at the same time, for instance).

As far as I know, Microsoft has always considered a "normal" window to be less than full-sized (maximized), possibly so that several can be visible on the screen at the same time, even though only one (normally the one in front) can be active at any given time. You can see this by looking at the properties for a shortcut ... the Run window gives you a choice of opening the program in: "Normal Window ", "Minimized" (program open, but its window reduced to a Taskbar button), or "Maximized ".

Why windows occasionally revert from maximized to normal is anyone's guess. I open almost all windows maximized, yet it happens to me from time to time, especially if I've changed my screen resolution for some reason.
