Travis uses Firefox 56 although Firefox 59 is installed on same system
问题 When running Selenium on Travis, it uses Firefox version 56. I need to use the latest version of Firefox, 59. Running apt-get update and upgrade does not solve this problem, but instead leaves the system with two different versions of Firefox, both 56 and 59. $ which firefox /usr/local/bin/firefox $ firefox --version Mozilla Firefox 56.0.2 but $ /usr/bin/firefox --version Mozilla Firefox 59.0.2 Anyone knows how to resolve this so that Firefox 59 is the only version available on the system?
