How do I uninstall the Snap Shots Add-On for Firefox?
Click on “Tools” at the top of your browser window, then click on “Add-ons”. Find “Snap Shots” and click on either “Disable” (to disable Snap Shots) or “Uninstall” (to permanently remove it). Afterwards, restart Firefox. Snap Shots should then be (depending on what you chose) disabled or uninstalled.
