Firefox bug with Selenium - Can't access dead object -

i've tried run tests selenium 2 , firefox 19. 1 of tests causes error "error: command execution failure. error message is: can't access dead object".

i'm reading it, seems bug in newest firefox's versions. lot of people have same issue, i've not found clear.

any heroe can us? maybe need change in "about:config"?

regards

i desperate same problem , didn't find solution although many people seemed have same problem.

i solved calling

webdriver.switchto().defaultcontent();

before calling findelement method (using java)
