Feature Request: Click to load embed

Add a click-to-load option for embeds. This is so that they don't load immediately after opening a new tab. Instead, you'll need to click the embed slot for it to load.

This can help if you want to embed a site that might slow your browser down every time you open a new tab, but you still want the convenience of having it right there on your new tab.

Great extension, and thank you for your time!
