Error with Webdriver/FXDriver utils.js leading to Firefox unresponsive script issue

While running browser tests with Watir webdriver and FXDriver, everything seems to be functioning well except for one test that loads a lightbox containing a large amount of HTML. When this lightbox opens, Firefox displays a popup indicating that Utils.js line 432 from FXDriver has become an 'unresponsive script', causing the test to time out. Instead of simply extending the dom.max_script_run_time, I would like to find a proper solution to fix the issue. Upon investigating the problematic line...

goog.string.canonicalizeNewlines = function(a) {
  return a.replace(/(\r\n|\r|\n)/g, "\n")
};

It is evident why Firefox is becoming unresponsive due to this code snippet, but the real challenge lies in finding a way to prevent it from happening. This function is called from various places, making it difficult to debug since it's invoked by Watir in a Firefox instance without Firebug. What steps can be taken to resolve this issue?

Modifying the file, adjusting the timeout, or reducing the amount of HTML content are not viable solutions.

Answer №1

Initiate Watir-WebDriver with Firebug feature activated.

To get started, first procure the Firebug XPI file and follow these steps:

profile = Selenium::WebDriver::Firefox::Profile.new
profile.add_extension "../path/to/firebug.xpi"
b = Watir::Browser.new :firefox, :profile => profile
