I\'m using Selenium Client 2.4.0 on Mac 10.6.6 with Firefox 5. Using the WebBackedSeleniumDriver, I\'m running a \"selenium.getEval\" command that causes a Firefox warning,
Go the hidden configuration page in Firefox by typing about:config in the address bar . (make sure that you are doing this for the profile you are using for selenium) In the 'Filter' box, type script_run_time. This will narrow the options to dom.max_script_run_time and dom.max_chrome_script_run_time. Right-click it and choose Modify. A box pops up. Change the number to something bigger like 40. This is the maximum time a script can run before Firefox considers it 'unresponsive'. If you can’t find the string in the about:config page, create it by right-clicking anywhere and then choose New—> Integer and enter there name and values (when asked)
