As above. My guess is I have tool bar on left side of screen and Firefox thinks it is on bottom and leaving room. First image is screen when I expand manually to full size. Second image is what screen looks like after clicking max box. Note second uses default background color I picked. on bottom is part of Word Window that I shouldn't be seeing.

Helped some. But now, sometimes switching between tabs, the bottom doesn't change. Also when I went to restart browser, an update occurred and created new version of file. Will delete again and see what happens.

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
