My home screen and all other browsing screens are so high and wide that I can't scroll down because the side slide bar is not on the screen. I have no idea how this happened! I can't find any articles that help me reduce the screen size that I can understand. There seems to be no solution option in firefox settings to adjust the screen size. The View tab does not help because it just offers zooming of the data on the screen, not the actual size of the screen.

I am going to use Chrome and/or MS Edge until this screen size issue is resolve by firefox, and I may not come back to using firefox any more - including cancelling my subscription to Mozilla VPN.

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).

Primary location used for the main profile that keeps your personal data (Root Directory on about:profiles). Note that in Windows "AppData" is a hidden folder.

It's useful to know some old-school keyboard tricks when things go awry. I this case, if you press Alt+Spacebar, Windows should drop down a control menu that allows switching between resizable and maximized for the window. Try Maximize if you can. Windows should then fit the Firefox window to the screen. If it's still too large, that would be odd.

(This doesn't fix a bad value saved in the xulstore.json file that cor-el mentioned, but should hopefully make it easier to navigate around the browser for the time being.)
