问题
I've tried to run my tests with Selenium 2 and Firefox 19. One of this tests causes an error "ERROR: Command execution failure. The error message is: can't access dead object".
I'm reading about it, it seems like a bug in newest Firefox's versions. Lot of people have the same issue, but I've not found anything really clear.
Any heroe can help us? Maybe we just need to change something in "about:config"?
Regards
回答1:
I was desperate about the same Problem and didn't find any solution although many people seemed to have the same problem.
I solved it by calling
webDriver.switchTo().defaultContent();
before calling any findElement method (using Java)
回答2:
This error generally comes when you do no switch back from frame and trying to access web elements directly.
Use driver.switchTo().defaultContent(); and then try to access the elements

I finally made a "cheat" to the browser.
I got the fail when Selenium clicked on a link and try to open the new page. What I've made is just simulate the click, doing a selenium.open("URL") which replace selenium.click("link=ButtonWhichOpenTheURL").
It seems to work by the moment

I am facing the same error on Firefox 23 while reopening a pop up browser window. The only workaround I did is closing the current selenium session and relaunching it again. It worked fine for me.
