Selenium Error: "unrecognized proxy type: MANUAL"

Question

I'm trying to learn how to run a selenium webdriver with a proxy server, but directly following the documentation with the provided code:

from selenium import webdriver

PROXY = "<HOST:PORT>"
webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
"httpProxy": PROXY,
"ftpProxy": PROXY,
"sslProxy": PROXY,
"proxyType": "MANUAL",

}

with webdriver.Firefox() as driver:
    driver.get("https://selenium.dev")

yields the following error:

selenium.common.exceptions.InvalidArgumentException: Message: Invalid proxyType value: MANUAL

Is the documentation outdated or is there something else I'm not taking into account here?

The documentation in question can be found here

Answer 1

By changing the value from MANUAL to manual you can get rid of below exception

Message: Invalid proxyType value: MANUAL

And if you get below exception then remove this line "ftpProxy": PROXY,.

Message: SessionNotCreatedError: InvalidArgumentError: Since Firefox 90 'ftpProxy' is no longer supported

Refer code below:

from selenium import webdriver

PROXY = "<HOST:PORT>"
webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
"httpProxy": PROXY,
"sslProxy": PROXY,
"proxyType": "manual",
}

with webdriver.Firefox() as driver:
    driver.get("https://selenium.dev")
