Msg: TypeError: e is null

[Saad Masood]

Hi,

    When I record an invalid user name and password test with Selenium IDE in Firefox 17 and try to click on the test, I get this error:

There was an unexpected error. Msg: TypeError: e is null

Url: chrome://selenium-ide/content/treeView.js, line: 124

I don't see these extensions when I type in 'about:config'

Change the settings to "default" for extensions.j...@seleniumhq.org.install-event-fired
and
extensions.selenium-ide.pluginsData

I am using Windows 7 Home Premium.

How do I add these extensions to Firefox?
