How To Fix Selenium Webdriver Not Opening A New Tab On Firefox 68.0 And Above?

After upgrading to firefox 68 my selenium python script broke, I wasn't able to open a new tab using the code that worked prior. from selenium import webdriver from selenium.webdri

Solution 1:

Turns out Mozilla made changes to future Firefox versions starting firefox 68,

so changing "browser.tabs.remote.autostart” value to false, simply won’t disable e10s (Multi-Process)

and as a result won't open a new tab in selenium.

you can read more about it here:

The solution is to delete the previous code and use this instead:

from selenium import webdriver
from selenium.webdriver.common.keysimportKeysimport os

os.environ['MOZ_FORCE_DISABLE_E10S'] = '1'
browser = webdriver.Firefox()

browser.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
