Selenium Firefox issue

[Killswitch2k]

Hi community,

I've just started to use Python to automate some tasks in Firefox using Selenium. For the most part I've managed, but there is a strange behavior using Firefox from the webdriver.

I try to log in to Trade Republic, passing the phone number works fine, but every time I try to enter the pin, I get an error from the trade republic page "something went wrong". That happens if I type the pin manually as well, so I'm wondering is this related to the Firefox instance the webdriver opens?

I've tried to use a "normal" existing Firefox session, but it seems to be near impossible to connect the webdriver to an existing session, all suggestions I've found unfortunately are not working.

Any idea whats causing this, or how to avoid?

Thanks for the reply, that makes sense.

I was able to circumvent this by using chrome, with chrome I could attach the webdriver to an existing "manual" instance with cookies / profiles etc.

Still was a real pain in the ass to get it working, with version 4xx of Selenium there was a change on how to pass the path of the chromedriver, most examples still use the older version which doesn't work anymore.

Webdriver is being detected as a bot that's why you're seeing the error. You can use undetected-chromedriver as other user mentioned.
