Tests failing with 'arguments[0] is undefined' in Firefox 35

[lukeis]

Originally reported on Google Code with ID 8387

What steps will reproduce the problem?
1. Use Capybara to 'fill_in' a field using Firefox 35
2.
3.

What is the expected output? What do you see instead?
Expected test to run normally, instead got:

  1) forms flow should work
     Failure/Error: login(@user)
     Selenium::WebDriver::Error::JavascriptError:
       arguments[0] is undefined
     # [remote server] http://127.0.0.1:59646/en/login line 68 > Function:1:1:in `anonymous'
     # [remote server] http://127.0.0.1:59646/en/login:68:20:in `handleEvaluateEvent'
     # ./spec/support/feature_spec_helpers.rb:4:in `login'
     # ./spec/features/forms_flow_spec.rb:7:in `block (2 levels) in <top (required)>'

Downgrading to FFox 34.0.5 eliminates the error.

Selenium version: selenium-webdriver gem 2.44.0
OS: Mac OS X 10.10.1
Browser: Firefox
Browser version: 35

If this is not easily reproducible let me know and I can write a test case. The one
I'm using now is part of a large project that would take ages to setup.

Appears as if any execution of JavascriptExecutor is causing this error to occur.  Verified
on Firefox 35; does not occur on Chromedriver or IEDriverServer.  Reverted back to
FF 34 as a workaround.

I'm seeing the same issue since upgrading to Firefox 35
Selenium version: 2.44.0 c~ bindings
OS: Window 7
Browser: Firefox
Browser version: 35

Sample code:
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;

namespace SeleniumSandbox2
{
    class Program
    {
        static void Main(string[] args)
        {
            var driver = new FirefoxDriver();
            driver.Navigate().GoToUrl("http://www.google.co.uk");
            ((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].scrollIntoView(true);",
driver.FindElement(By.CssSelector("#gb_70")));
       }
    }
}

I also see Firefox 35 failing when executing javascript. In the Firefox console, I see
this error: "Security wrapper denied access to property length on privileged Javascript
object. Support for exposing privileged objects to untrusted content via __exposedProps__
is being gradually removed - use WebIDL bindings or Components.utils.cloneInto instead.
Note that only the first denied property access from a given global object will be
reported." This appears to be related to a deprecated javascript property in Firefox:
"http://codeverge.com/mozilla.dev.b2g/notice-do-not-add-new-instances-of-exposedpro/1992161"
 In the file selenium/javascript/firefox-driver/js/firefoxDriver.js I do see a reference
to __exposedProps__. This is making our Firefox Selenium Webdriver testing unusable.
Perhaps this other method Components.utils.cloneInto can be used?

I can confirm this issue and downgrading Firefox (for me to version 34.0.5) causes test
scripts to once more work

Same issue here; 34.0.5 works ok.

Hi all -- happening for me also, I cannot execute any JS code with FF 35.0 and Selenium
2.44.0. Is there any fix planned ? Thanks
