Mozilla Firefox Changed My View Settings. I Want My Old View Back!

[icecream]

For awhile my homepage on Mozilla Firefox for Windows has been two rows of eight squares each with sites recently visited. I had those boxes at a nice big view setting so they could be easily seen. Today the size of those squares shrunk to a much smaller size I don't want. They must have done it to match the width of Google search bar above it but my monitor has space for wider. And something is off when I try to change, clicking on manage settings does nothing and just gets that window retracted. Firefox's help support section is a joke, says how to remove or add a site to your home page but not how to edit the size of the site display square.
