Summary – How to Get Rid of the Firefox Close Tab Warning

  1. Open Firefox.
  2. Click the menu button at the top-right.
  3. Choose Settings.
  4. Uncheck the Confirm when closing multiple tabs box.

Our guide continues below with additional information on shutting off the Firefox multiple tabs warning, including pictures of these steps.

Tabbed browsing is the standard option when you use a Web browser on your computer.

This allows you to have multiple Web pages open at the same time, and it makes it easy to switch between those pages by clicking the appropriate tab.

But this creates a new prompt in Firefox where the browser will alert you that there are multiple tabs open when you attempt to close out of the browser.

This serves as a helpful reminder if you actually only wanted to close the current tab instead of the entire browser.

However, if you actually intend to close the whole browser, this additional step can be somewhat of a nuisance.

Fortunately, there are a couple of ways that you can prevent this check from occurring.
