How to enable firefox extensions in Selenium?

Question

I installed an extension in firefox but when Selenium opens firefox it starts without the extension, is there any way that Selenium can start firefox with the extension that is installed or make it "install" the extension on start? I’m using the Selenium library for python

options = Options()
self.browser = webdriver.Firefox(options=options)
url = 'https://www.google.com/'
self.browser.get(url.lower())

Answer 1

options = Options()
browser = webdriver.Firefox(options=options)   
browser.install_addon('caminho do arquivo .xpi')
browser.get('...')
