I cannot get the freeze first row function to work, even though I found it under “Tools - Customise”

If you want to freeze just the first row, simply select View |Freeze Cells |Freeze First Row.

You can undo this by unchecking View |Freeze Rows and Columns.

Active cell must be in row 2.

Edit: My comment don’t applies for @robleyd answer (his answer is correct), but when choosing menu View - Freeze Rows and Columns.
