This morning, I set out to get selenium working on my Mac. It didn’t work right out of the box, so here is what I did to get it working
Selenium won’t work with firefox 3 without some configuration. It is actually hardcoded to firefox 2. So I’ve updated the configuration to work with firefox 3.0.x, and created a new jar to assist anyone who is going down this path. If you are working with ruby and have the Selenium gem installed, you can replace $GEMHOME/gems/Selenium-1.1.14/lib/selenium/openqa/selenium-server.jar.txt with this jar. After that, everything should run great for you.
Keep in mind that you’ll have to make some changes to the path if you are running a newer version of the Selenium gem. Let me know if you run into anything else.
