_I mainly use FirePath to create my CSS and XPATH locators. I also use the built in tools in Opera and Chrome._
I have an out of date and old post over on EvilTester.com Use firefinder to help you construct Selenium CSS Selectors. I rarely delete out of date posts, but I don’t use Firefinder any more.
In Firefox use FirePath, this also runs as a Firebug addin and allows you to explore and experiment with CSS and XPath locators.
There I am, figuring out how to debug my FitNesse automation from within eclipse. And up pops the Firefox ‘update failed dialog’ and interfering with my automation.
A bane and a pain when using Selenium RC. But with WebDriver there are easy ways round this.
Start firefox with a profile and set the “app.update.silent” firefox property to true.
The update error will still happen, but at least firefox won’t try and tell your automated processes about it.
