Java Applets and Firefox unresponsive Error message

I have a Java Applet. On IE, it works fine, On Firefox, Firefox frequently given a dialog box saying "The plugin is unresponsive/hung. Do you want to continue waiting for it or kill it?".
In order to troubleshoot, it would be useful to know how firefox detects that the plugin is unresponsive - has Firefox published this info anywhere?
I found this page - https://developer.mozilla.org/en-US/Add-ons/Plugins/Out_of_process_plugins/The_plugin_hang_detector
However this talks about killing the plugin & not giving this error message.

How to Stop Script Errors on Firefox

Execute Selenium Commands on a Browser that is already open

I am looking for an example code that will allow me to run Selenium commands against a browser that is already open.
Typically when you start testing with Selenium it opens a new instance of the browser. But I am looking
for a solution where you would run the script and it will just start executing its codes on whatever browser and tab is currently visible.
Is that possible?

As per my knowledge this is not possible with selenium.
You have to open browser during the test script only otherwise it won't be able to identify or capture already opened browser's object.

No its not. There is an old issue still open since 2009.

Automation server can't create object - Microsoft JScript runtime error

I am trying to run a Java webstart application which is launched from a html page. While loading I get an alert with the message "Automation server can't create object" a couple of times after which the applications starts and works fine. The alerts come up only on one of the workstations. Any pointers on where I should look?
Regards,
Dutch

try the following IE setting: "Initialize and script ActiveX control not marked as safe."

May or may not apply to your case, but there are reported problems with the JScript Runtime throwing up errors when starting up Applets or Java WebStart applications when you have specific network settings.
Every now and again, there's a Windows Update that generates such a bug and another one that follows to fix it and you'll see some of these errors. Yours might be one of these.
Usually the workaround in-between is to either:
go to IE's Network Settings and uncheck "auto detect settings" or any PAC file setting
or go to the Java control panel's Network Settings and disable "Use browser settings" or other settings to use a direct connection instead.
Obviously, that workaround is only valid if you do not have to go through a proxy...

Testing onbeforeunload events from Selenium

I'm trying to write a Selenium test for a web page that uses an onbeforeunload event to prompt the user before leaving. Selenium doesn't seem to recognize the confirmation dialog that comes up, or to provide a way to hit OK or Cancel. Is there any way to do this? I'm using the Java Selenium driver, if that's relevant.

You could write a user extension (or just some JavaScript in a storeEval etc) that tests that window.onbeforeunload is set, and then replaces it with null before continuing on from the page. Ugly, but ought to get you off the page.

I've just had to do this for an application of mine where the onbeforeunload handler brings up a prompt if a user leaves a page while a document is in an unsaved state. Python code:
driver.switch_to.alert.accept()
The Java equivalent would be:
driver.switchTo().alert().accept();
If the alert does not exist, the code above will fail with a NoAlertPresentException so there is no need for a separate test to check the existence before accepting the prompt.
I'm running Selenium 2.43.0 but I think this has been doable for a while now.
In cases where I don't want the prompt to come up at all because that's not what I'm testing, I run custom JavaScript in the browser to set window.onbeforeunload to null before leaving the page. I put this in the test teardown code.

faced same problem with "beforeunlaod" event listner, LUMINUS! a chrome addon that helps me just block the event listener in the plugin thats all..

When I was confronted with limited control which I had over browser using Selenium, I turned to MozLab plugin which solved my problem if only for one browser platform.
