I can reproduce the problem in a ppc64el cloud instance, and it can be
observed in firefox's autopkgtest results, too
(http://autopkgtest.ubuntu.com/packages/firefox/focal/ppc64el).
The problem is not a version mismatch though. The firefox-geckodriver
package is built from the same source package as firefox, and it works
on other architectures.

Title:
geckodriver version is incompatible with firefox in ppc64el
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Hi all,
An application my team and I are developing makes use of a firefox
selenium driver in python for ppc64le architectures. I noticed that
this module in our application was not functioning due to an inability
for the python library to connect to the geckodriver. I also noticed
that the x86_64 version of our app is functioning with the same
version of firefox and geckodriver.
The python error we are seeing is the following:
TimeoutException: Message: connection refused
The timeout was set to 10 seconds, so I updated it to 40, and then 300
and got the same issue.
geckodriver starts up without any errors. but selenium can't seem to
connect to it.
Upon deploying an old version of a docker container of our app (based
on ubuntu 18.04), I compared versions of the old version, which
selenium worked, vs the new version which selenium does not work.
What I found was that although the apt packages for firefox and
geckodrivers seem to point to a v75.0 build of firefox, the version
in geckodriver did not change between version upgrades.
so,
firefox version changed 72.0.2 -> 75.0
geckodriver did not 36.0 -> 36.0
I suspect this is the source of the issue, because if firefox changes
and the geckodriver remains the same, they won't sync up right.
