#Mozilla firefox critical error red screen remove download#

The problem was resolved by moving from Selenium 2.24.1 to Selenium 2.25.0Īs the selenium change is just download the jar file and run it instead of the old one,it's worth trying this as a quick and easy troubleshooter - if it doesn't help, just switch back. Running on Ubuntu, this happens auto magically along with other upgrades but I believe this was the critical change. My problem started when I moved from FF 15 to FF 16. It appears Selenium and Firefox have difficulty talking to each other - I suspect Firefox 'evolve' changes over a number of releases, so backward and forward compatibility are not always guaranteed, and incompatibility always seems to generate the same error. at .invoke(Method.java:601)ĭon't know if you resolved this problem, but I have just resolved the same issue from the other side.

Perhaps it has something to do with localhost:7055 not existing? I am unsure where to go from here. This is what my /etc/hosts says: 1 127.0.0.1 localhost.localdomain localhost It doesn't seem like port 7055 on localhost even exists: However, none of the above solves the problem. Supposedly downgrading firefox helped some people, but I do not wish to do this. Sshd_config shows having X11Forwarding as true. This works as I can see xclock being displayed in the VNC.įirefox is correctly located in /usr/bin/firefox The bash script basically just does an export DISPLAY=mydisplay:1.0. Placed a bash script in Jenkins to run before running selenium tests. There are various threads here that seem to have the exact same problem, and I think I've tried most of them.

And this will bring up firefox and the tests just fine. The funny thing is that I can ssh in manually into the box, temporarily copy the magic cookie from another user on the box (to get an X tunnel), do an export DISPLAY=mydisplay:1.0, then launch my selenium tests using ant. I am using selenium-java-2.25.jar, firefox 10, linux OS. The end idea is to run the webtests on this box entirely, and also take some screenshots of errors.

Here I am trying to run my Selenium Webdriver tests, but it tells me that I have errors in launching firefox. It seems like Jenkins would ssh in and execute commands described in the specific job that's running.
