How to disable extensions and themes

Disabling an extension or theme will turn it off without removing it:

  1. Click the menu button New Fx Menu and choose Add-ons. The Add-ons Manager tab will open.

  2. In the Add-ons Manager tab, select the Extensions or Appearance panel.
  3. Select the add-on you wish to disable.
  4. Click its Disable button.
  5. Click Restart now if it pops up. Your tabs will be saved and restored after the restart.

To re-enable the add-on, find it in the list of Add-ons and click Enable, then restart Firefox if required.
