Firefox as a Driver got Error `WebDriverException : Process unexpectedly closed with status 255`

[aulia-adil]

So I got this problem when I want to use Firefox as the driver. This problem has ever been asked in here in Stackoverflow and I think the problem is because mismatch version between Firefox and Geckodriver. I think we can't use latest version in Firefox installation.

I don't think it's a mismatch in the Firefox and Geckdriver so much as the Selenium package being pegged at v3.14. I got around this issue once by upgrading Selenium. I should warn you that you may still run into the same Error code anyway if running the container in a CI or similarly hosted environment like GitHub Actions. For this, you'll want to start the selenium driver with some additional flags, such as --headless and --no-sandbox. Look to this question for more info.
