Unable to Obtain a Stable firefox connection in 60 seconds

[umairmm]

I am getting this error on centos. I am using Selenium 2.46.2 and Firefox I have tried firefox 39, firefox 38.0 and firefox 33. But it is giving the same error. Here is my code:

Selenium::WebDriver::Firefox::Binary.path='/usr/bin/firefox'
browser = Watir::Browser.new :firefox # should open a new Firefox window
browser.goto self.url

I am seeing this too on CentOS 7.1.1503

You found any solution?

What we have done is revert back to FF 31.6.0 until a fix is in place, no sign of the unstable connection there, still using selenium 2.46.2

@umairmm you might add your error log output when you can, to ensure that it is the same issue

[umairmm]

my log is:

This is still occurring in 2.47.0 on Cent OS 7

In centOS 6, with gem 'selenium-webdriver', '2.47.1' and firefox 33 I get the same error message:

"unable to obtain stable firefox connection in 60 seconds" ...

The same gem version and firefox versión in windows 7, it works.

Hi!

centos version 6
selenium-webdriver v.2.47.1
and... when I update firefox version to last version available: (yum install firefox). v. 38.1.0
and exec 'dbus-uuidgen > /var/lib/dbus/machine-id'

it works!!!! =D

I faced the same issue. Downgrading the Firefox to the previous version solved my problem on Mac machine.

I've seen this crop up today, given ruby gem version 2.53.1 and Firefox 47.0.0, on Ubuntu 14.04. Downgrading to Firefox 46.0.1 has temporarily solved it...but clearly I'd like to be able to use latest Firefox.
