I've seen various comments on forums stating that the version of Geckodriver 0.26 available at:
(https://github.com/mozilla/geckodriver/releases/tag/v0.26.0)
is only for x86 machines. I've done the other steps, and for geckodriver I've downloaded and moved the binary to /usr/local/bin, but it does not appear to be executable nor does chmod +x seem to make it executable. Is there any guidance on this?
