I tried by changing selenium server to 2.35 or 2.39 and I upgraded ff to 26. But it doesnt work

When I degrade my ff version to 24, my scripts are working fine.

1. I would like to know why it is happened and root causes
2. I would like to know what is permanent solution for above 24 version of ff.

Please help me on this.

Answer 1

Seems like an issue with webdriver version. Can you try once with latest bindings i.e 2.40.0. To get more info on webdriver version and supported firefox version please go throgh webdriver release notes :http://selenium.googlecode.com/git/java/CHANGELOG

Answer 2

I had the same message before and I actually found out that the problem was the hosts file in my Mac (/private/etc/hosts). I don't know the reason but somehow it was pointing to an invalid IP in my network. Replacing the line for localhost pointing to 127.0.0.1 solved the problem for me. In resume, I was trying to access the Firefox in some other machine (odd!)
