% is the wildcard search syntax in SQL Server. When you use it with LIKE operater it will return the values as below;

SELECT * FROM table WHERE FirstName LIKE '%'  -- Will return all the rows
SELECT * FROM table WHERE FirstName LIKE 'a%'  -- Will return firstnames starts with a

etc...

So your @firstname variable may be used in a wildcard search in the stored procedure. Hard to say what exactly it does without seeing the remining part of the procedure
