Hi, the button has been moved to the toolbar and is combined with the stop 'x' button. If you can't see it, have a look in Customize mode. If it's there, you can drag it to anywhere you like. If you don't see it click on Restore Defaults [[Customize Firefox controls, buttons and toolbars]] ''If your question is resolved by this or another answer, please take a minute to let us know. Thank you!''
