Firefox is supposed to open in the same mode as when it is closed. This is not happening and while not a terrible problem it is annoying to have to resize the display every time I open the program. Nothing I do changes the situation.

Is this a bug in the latest update ?? If not, how do I correct the problem??

More info about RFP:

If this doesn't apply then 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).
