Serenity won't work with vanilla Ubuntu 22.04 and Firefox

[gurgl]

Because how Firefox is installed by default in Ubuntu its now impossible to run Serenity with Firefox on Ubuntu 22.04. This is because of how Snap's security model work and is described here https://bugzilla.mozilla.org/show_bug.cgi?id=1766125

There must be means to provide geckodriver with an argument

geckodriver --profile-root

I haven't had time to dwell into the details, but setting to "~/tmp" works for me. I had to bypass this limitation by creating a script geckodriver_tmp.sh:

#!/bin/sh
/snap/bin/geckodriver --profile-root ~/tmp "$@"

When doing this autodownload of drivers cannot be turned on so shut it off. So in src/test/resources/serenity.conf file make sure the following are added:

drivers {
  linux {
    webdriver.gecko.driver = /pathto/geckodriver_tmp.sh
  }
}

webdriver.autodownload = false
