Hi Ben,
Just a few thoughts.
1. Have you tried a newer version of the selenium-webdriver gem (if
compatible)? I see several newer versions than 2.53.4
➥ gem search selenium-webdriver -ra | grep -e "^selenium-webdriver ("
> selenium-webdriver (3.4.0, 3.3.0, 3.2.2, 3.2.1, 3.2.0, 3.1.0, 3.0.8,

> 2.17.0, 2.16.0, 2.15.0, 2.14.0, 2.13.0, 2.12.2, 2.12.1, 2.12.0, 2.10.0,
> 2.9.1, 2.9.0, 2.8.0, 2.7.0, 2.6.0, 2.5.0, 2.4.0, 2.3.2, 2.3.0, 2.2.0,

> 0.0.2, 0.0.1)
2. Have you tried to check and possibly change what the selenium-webdriver
gem is doing? Consider dumping the command arguments before it shells out
to the firefox bin (assuming this is what it does). If you have access to
the gem locally and want to open it in your editor, you can run:
➥ bundle open selenium-webdriver
If you need to see where the source is and don't have direct access (e.g.
running through a docker container):
➥ bundle show selenium-webdriver
3. My Firefox shows as version 53.0.3; a bit newer than your 47.0.1 .
Assuming the "-foreground" option is being passed to the firefox-bin
binary, I can verify it doesn't appear to be a valid argument.

Hope this helps,
