Is there a way or a tool to do UI automated testing on Firefox sidebar? We used Firefox add-on SDK (https://developer.mozilla.org/en-US/Add-ons/SDK) to implement a sidebar with a variety of UI elements (buttons, checkboxes, texts) in Firefox. I am surveying a solution to do UI test automation on this sidebar, but with no luck. For example, Selenium IDE can only record actions performed on a regular web page in Firefox, but not any actions performed on the sidebar in Firefox that implemented by using Firefox add-on SDK. Anyone knows of any solution that can do that?
Thanks!
