title: Slow in switching tabs with Python 3 selenium in Chrome 79
body: <p>Python version: 3.7.1</p>
  
  <p>Chrome Version: Latest (79.0.3945.79)</p>
  
  <p>It takes 4 seconds to switch tabs with "switch_to.window" command: (in both head mode and headless mode)</p>
  
  <pre><code>browser.switch_to.window(browser.window_handles[-1])
  </code></pre>
  
  <p>It does not have any effects when I try to switch windows with send keys:</p>
  
  <pre><code>browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + '2')
  </code></pre>
  
  <p>or</p>
  
  <pre><code>actions = ActionChains(browser)      
  actions.key_down(Keys.CONTROL).send_keys('2').key_up(Keys.CONTROL).perform()
  </code></pre>
  
  <p>There are only 10-20 tabs. It surprises me that it takes 4 seconds to switch tabs</p>
  
  <p>How can I speed up the process?</p>
