I am using Firefox 31, GWT 2.7, GWT Bootstrap 2 and run with super dev mode. Sometimes I click on some widgets and my browser freezes and Firebug's Script panel shows the following:

Firebug's Script panel freezing browser

I would like to know why this is happening and how to fix it.

Firebug stops the JavaScript execution automatically on the debugger keyword. You can continue the script execution by clicking the continue button (the button with the blue triagle within the panel toolbar) or by hitting F8 or you just reload the page.

To avoid that you have the following options:

  1. Remove the debugger keyword(s) from the code
  2. Clicking the Disable button as suggested in the notification
  3. Deactivate the Script panel (by right-clicking the panel tab and clicking Enabled in the popup menu to uncheck it)
  4. Deactivate Firebug for the current website (by clicking the stand-by button in the upper right corner or hitting Shift+F12)
  5. Deactivate Firebug within the Add-ons Manager (available via Ctrl+Shift+A)

  • You have to continue the script execution or reload the page to unfreeze it. If your code does not contain `debugger` keywords, you need to check where they come from and remove them there or download a release version of the third-party code you use. (The file name is displayed within the *Script* panel toolbar. Unfortunately your screenshot doesn't show it.) You don't have to tell your users about the `debugger` keyword, as that is only relevant for people using a DevTool like Firebug, (which normal site users don't do). Also, know that every DevTool has a debugger, also the one in Chrome. – Sebastian Zartner Feb 13 '15 at 06:55
