How do I switch to the active tab in Selenium?

This actually worked for me in 3.x:

driver.switch_to.window(driver.window_handles[1])

window handles are appended, so this selects the second tab in the list

to continue with first tab:

driver.switch_to.window(driver.window_handles[0])

Some possible approaches:

1 - Switch between the tabs using the send_keys (CONTROL + TAB)

self.driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)

2 - Switch between the tabs using the using ActionsChains (CONTROL+TAB)

actions = ActionChains(self.driver)      actions.key_down(Keys.CONTROL).key_down(Keys.TAB).key_up(Keys.TAB).key_up(Keys.CONTROL).perform()

3 - Another approach could make usage of the Selenium methods to check current window and move to another one:

You can use

driver.window_handles

to find a list of window handles and after try to switch using the following methods.

- driver.switch_to.active_element      - driver.switch_to.default_content- driver.switch_to.window

For example, to switch to the last opened tab, you can do:

driver.switch_to.window(driver.window_handles[-1])

The accepted answer didn't work for me.
To open a new tab and have selenium switch to it, I used:

driver.execute_script('''window.open("https://some.site/", "_blank");''')sleep(1) # you can also try without it, just playing safedriver.switch_to.window(driver.window_handles[-1]) # last opened tab handle  # driver.switch_to_window(driver.window_handles[-1]) # for older versions

if you need to switch back to the main tab, use:

driver.switch_to.window(driver.window_handles[0])

Summary:

The window_handles contains a list of the handles of opened tabs, use it as argument in switch_to.window() to switch between tabs.
