You can enable them via Theme Options > Page Options / Blog Options (Single Post Settings) / Portfolio options / WooCommerce Options (Single Product Settings) / Event Calendar Options > Breadcrumbs Bar Settings respectively, depending on where you want them to appear.

All you have to do is to have the Breadcrumbs option enabled, where applicable, and then the external plugin’s settings will override the native function. Both of these external plugins provide multiple options for you to set up your breadcrumbs as you wish.
