I am using Selenium 2.45 with Firefox 35.0.1 headless browser. Things are fine in dev and test environment, but in production, I am getting error.
Driver info: driver.version: FirefoxDriver
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows:

Production Environment:
1) Downloaded firefox-35.0.1
[prod@prod ~]$ ls /usr/local/
bin etc firefox firefox-35.0.1.tar.bz2 games include lib lib64 libexec sbin share src
2) soft linked to /usr/bin/firefox
[prod@prod ~]$ ll /usr/bin/firefox
lrwxrwxrwx 1 root root 26 Jun 11 15:59 /usr/bin/firefox -> /usr/local/firefox/firefox
[prod@prod ~]$
3) Ran Xvfb
[prod@prod ~]$ ps ax |grep Xvfb
15425 ? S 0:00 sudo Xvfb +extension RANDR :1 -screen 0 1024x768x24
15426 ? S 0:00 Xvfb +extension RANDR :1 -screen 0 1024x768x24
23102 pts/6 S+ 0:00 grep Xvfb
Test Environment:
[root@vc-stage ~]# ll /usr/bin/firefox
lrwxrwxrwx 1 root root 26 May 24 21:32 /usr/bin/firefox -> /usr/local/firefox/firefox
[root@stage ~]#
[root@stage ~]# ls /usr/local/
bin etc firefox firefox-35.0.1.tar.bz2 games include lib lib64 libexec sbin share src
[root@stage ~]#
[root@stage ~]# ps ax | grep Xvfb

27393 ? S 0:01 Xvfb +extension RANDR :1 -screen 0 1024x768x24
[root@stage ~]#
The only difference between test and prod is; in test I am running everything from a root user. In prod, I am running by a sudo user.
Update: The error message is gone without any changes whatsoever, Duh. Now, it is simply not creating the firefox Driver.
Everything was all right. 1 package was missing in production- "dbus". After installing and configuring the package, everything worked fine.
