1. Find the element
https://blog.csdn.net/qq_32897143/article/details/80383502
2. Explicit wait and implicit wait
Display waiting: execute when the element is found within a period of time, and no error is reported.
Implicit waiting: similar to time.sleep(10), it waits for a period of time before starting to find elements.
3. Close (close and quit)
close: Close the current page.
quit: Close the browser.
4. The presence of an embedded frame makes it impossible to locate the element
# 切换内嵌frame
fr=browser.find_element_by_xpath("//iframe[contains(@src,'https://uac.10010.com/portal/homeLoginNew')]")
browser.switch_to.frame(fr)

profile=webdriver.FirefoxOptions()
profile.add_argument('-headless') #设置无头模式
#设置代理服务器
profile.set_preference('network.proxy.type', 1)
profile.set_preference('network.proxy.http',IP)#IP为你的代理服务器地址:如‘127.0.0.0’，字符串类型
profile.set_preference('network.proxy.http_port', PORT) #PORT为代理服务器端口号:如，9999，整数类型
