browser = webdriver.Firefox(executable_path="C:\Users\Public")

This line of code will not work as the executable_path parameter should specify the path to the geckodriver executable, not just the path to a folder. Here's an example of how to specify the path to the geckodriver executable in Windows:

from selenium import webdriver

# Replace this with the path to your geckodriver executable
geckodriver_path = r"C:\path\to\geckodriver.exe"

# Create a new Firefox browser instance
browser = webdriver.Firefox(executable_path=geckodriver_path)

Note that the 'r' before the path string is used to indicate a raw string, which prevents backslashes from being interpreted as escape characters.
