The ": Message: Can’t load the profile." error is now gone. So, for now, with latest Firefox ESR 52.6.0, these pins are working: Since they don't tell which Selenium version is compatible with gecko 0.17.0, I kept reading the changelog until I found Note that geckodriver v0.16.0 is only compatible with Selenium 3.4 and greater. Sudo wget -c -O - | sudo tar -xz -C /usr/local/bin/ In version v0.18.0, there's geckodriver now recommends Firefox 53 and greater so I downloaded v0.17.0 directly into my /usr/bin folder: Since I'm stuck in Firefox 52.6.0 ESR, I searched for "Firefox 53" in their full changelog.

They have a changelog but it's not in all releases that they give an insight of which versions of FIrefox/selenium are compatible or not. It's hard to make it work because you need to have a specific Firefox, Geckodriver AND selenium configuration! So how did I check which versions should be used? I started with geckodriver. I just got a specific configuration that is working so far! Don't know if it's going to have problems along the road but it may be useful to other people.
