...implies that the Mozilla Firefox executable was unaccessable due to wrong permissions.

While working with Selenium v3.x, GeckoDriver and Firefox you have to consider certain facts as follows:

• Instead of Mozilla Firefox binary (i.e. firefox.exe) you need to pass the absolute path of the GeckoDriver binary through the argumentexecutable_path within single quotes (i.e. '') along with the raw (r) switch.
• You need to download the latest release of GeckoDriver from this link and ensure that GeckoDriver have required permissions to be accessed by non-root user.
• Always execute your TestCases/TestSuite as a non-root user.

• Your effective code block will be as follows:

  from selenium import webdriver
  driver = webdriver.Firefox(executable_path=r'C:\path\to\geckodriver.exe')
