We are using Selenium for testing JavaScriptMVC app and met "Permission denied to access property 'steal'" problem in Firefox 17..
Looks like this problem appears if win.top.opener exists and (I'm not sure about this part) but has different origin. We could reproduce the problem without Selenium - just open sequence of two windows.
We found that code that causes the problem presents in steal.js from recent JavaScriptMVC bundle, but doesn't present in latest steal.js code.
Yes, I could see discussion here but questions are:
1. Does any JavaScriptMVC related fix exists ?
2. Does it make sense to switch to newer version of steal.js?
3. Why we have this problem in Firefox only? (not in IE or Chrome)
Any other suggestions?
Thank you
