You can try the following, but error messages will pop up in dialog boxes instead of showing in the respective tab.

  1. Type about:config into the address bar and press Enter.
  2. To bypass the warning, press the big button labeled "I'll be careful, I promise!".
  3. In the search box, paste browser.xul.error_pages.enabled
  4. In the search results, double-click browser.xul.error_pages.enabled to set its value to false.
