Firefox on iPhone uses Webkit. It's basically a Safari skin.

> It is the first Firefox-branded browser not to use the Gecko layout engine as is used in Firefox for desktop and mobile. Apple's policies require all iOS apps that browse the web to use the built-in WebKit rendering framework and WebKit JavaScript, so using Gecko is not possible.

Good to know. I am not sure why that was relevant to the page load issues of the Stripe dashboard since I didn’t compare it to Safari

Hopefully Apple's policy ends soon.

Last time I checked Firefox for iPhones was just a UI over Safari engine. Did things change?

No, it is still using Safari WebView, but Apple may be forced to change that policy in the near future if we're lucky.

how are people so confidently wrong about stuff like this?
