Running Selenium WebDriver tests with Firefox no longer works on Ubuntu

Question

Running Selenium (Webdriver) tests with Firefox locally on my Ubuntu workstation no longer works.

The exact same setup worked before, but I think Firefox was upgraded at some point (it's now 16.0.2 from the Ubuntu package 16.0.2+build1-0ubuntu0.11.04.1), after which it stopped working. In normal use Firefox works ok.

With Webdriver, when I run a testcase (via my IDE), an empty Firefox window is opened, but the test does not start. After 45 seconds, it times out with this error message:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

In our base test class, the FirefoxDriver is initialised simply like this:

new FirefoxDriver(new FirefoxProfile())

...although I also tried pointing to an existing Firefox profile dir (something like /home/jonik/.mozilla/firefox/vds3ono5.default) with the same result.

Any ideas how to get the tests running again?

• Selenium (Webdriver) 2.23.1
• Firefox 16.0.2
• Ubuntu 11.04

Answer 1

Firefox 16 isn't supported in v2.23. You will have to either upgrade to v2.26, or downgrade Firefox.
