how to disable firefox close multiple tabs confirm dialog box


The Problem

In Firefox when attemping to close multiple open tabs Firefox pops open an annoying dialog box prompting you to answer... "You are about to close 2 tabs. Are you sure you want to continue?"

The Solution

  1. Type about:config into Firfox's address bar and click enter.
  2. On your keyboard click Control-F to bring up the search bar.
  3. Search for browser.tabs.warnOnCloseOtherTabs
  4. Double click it to change its value to False

Done! For now on Firefox will not prompt you when closing multiple tabs.
