selenium.common.exceptions.SessionNotCreatedException - Issues with GeckoDriver

[gohjiayi]

Hi, thanks for the codes! Was trying to test this package out and faced this issue when running the sample codes in the README. I am not very familiar with web scraping but seems to be some issue with GeckoDriver, not too sure on why this error is popping out. Besides that, I would like to also check if this package works with Facebook groups (not pages). Please help!

>>> json_data = facebook_ai.scrap_to_json()

There are some possible reasons for that error like:

• Firefox is not installed on the default path.
• Firefox is not installed in your system.
• Firefox access is admin only
• Firefox is not installed with the same name
• Firefox version is not updated

Currently, it scrapes only Facebook pages. Soon, will add the feature for public groups as well.

Thanks for your help, can I ask if this applies to Firefox only? Since I do have chrome installed and I assumed it will work with that...

[shaikhsajid1111]

Yeah it will, just replace "firefox" with "chrome"

Got it! Thanks for your help, hope to see the new feature for public groups soon. 👍🏻
