That's a winner, Rick!! It worked!! I wouldn't have thought it would, but sure did! Thanks for hanging in there to help me though this traumatic situation (can't afford a therapist). Thanks to ALL -- for all the help! Ain't Mozilla / TB wonderful! Merci!

Maybe this will make it more understandable:

Thanks, Lin, as best I can see in the fuzzy image (minimizing a window) , it does work. Now to see if I can scale and automate it for bookoo EMLs! Thanks!

It's a video. You have to click on it.

Ahhhh! That works perfectly! As does the minimized window drag and drop! Thanks.

Here is a link to using the features of your operating system that make placing more than one window on 6your screen a doddle.

Here are some other approaches suggested by the google AI for windows 10

To tile desktop windows in Windows 10, you can use Snap Assist by dragging a window to the edge or corner of the screen, or by using the shortcut Windows key + Arrow keys. Alternatively, you can press Windows key + Z to open the Snap Layouts menu and select a desired layout. For more advanced tiling, you can install Microsoft PowerToys and use the FancyZones feature to create custom layouts and shortcuts. Using Snap Assist (Built-in Method) 1. Drag and Drop: Click and hold a window's title bar and drag it to the left or right edge of your screen until you see a transparent outline. Release the mouse button to snap the window to that half of the screen. 2. Snap to Corners: Drag a window to one of the four corners of the screen to snap it into a quarter of the screen. 3. Windows key + Arrow keys: Press the Windows key + Left Arrow or Windows key + Right Arrow to snap the active window to the left or right half of the screen, respectively. 4. Windows key + Z (Snap Layouts): Press Windows key + Z to bring up the Snap Layouts menu. Select a desired layout (e.g., three windows side-by-side or a two-by-two grid) from the menu that appears. Windows will then allow you to fill the rest of the layout with other open windows.

Thanks, Matt, for the youtube. Mozilla support bonus -- I'm learning Windows, too. I'd heard / seen something about "snap" but never thought it something I needed. Learned also that drag and drop works however you can pop-up a window (no need to establish some kind of internal "relationship" -- one screen knows of the other). Really do appreciate it!
