Hi ,

  I am Automation developer , I am using firefox with selenium , every time selenium tries to close the browser it throws an error "Plugin Container has stopped working"

Problem event name :APPCRASH Application Name: plugin-container.exe Application version: 31.0.0.5310 Fault Module Name: Mozalloc.dll Exception code :80000003


Then when I have tried performing it manually , then too I had faced same issue, let me know if there is any fix available, I don't want to roll back whole project on older version, which might have some more issues pending to be resolved.

Regards Shekhar

Do you need the plugin-container and plugins to do the testing or would it work without plugins?

If plugins are used, what plugins in particular?

more options

current test cases are static and just verifies the content of page and displayed buttons.

Any solution , I have kind'f tried everything by now . except deleting the plugin container from hard drive, I am not sure if I'll do that and it will appear again once the browser will get initialized , any Mozilla expert online to reply with atleast one good suggestion.

I have deleted the plugin.exe , no pop up anymore , I am sure that I have to pay the price later when I will have to play the videos , but as no support from Mozilla I had to do it . No thanks to you Mozilla support , you have done a good job ruining this product.

You should be able to achieve this by disabling the plugins (Never Activate) on the about:config page to prevent loading this plugin and the plugin-container. If you need to create new profiles then you would have to use a user.js file in the browser\defaults\profile folder to disable the Flash plugin (plugin.state.flash = 0).

For the plugin-container you could use:

  • dom.ipc.plugins.enabled.npswf32.dll = false
