Should I pick desktop or mobile?
Pick the device most of your traffic uses. Mobile burns are recorded at phone size, usually in a phone-sized browser window on the reviewer's computer, sometimes on their own phone; desktop burns are recorded in a browser on a computer.
Each Site Burn is either desktop or mobile. You set it when you submit and can't change it afterwards, so check your analytics first. If 70% of your visitors are on phones, that's where the friction is.
Desktop
The reviewer records in Chrome, Edge, Firefox or Safari on a computer, with their microphone. If your site blocks being embedded, they use the BurnTest Recorder extension or a window-share fallback. You don't need to do anything.
Mobile
Your site is shown at phone size (an iPhone-sized screen) while the reviewer talks through it. Most reviewers record in a phone-sized browser window on their computer with the BurnTest Recorder; some record on their own phone with its screen recorder and upload the file. Either way the video is portrait, phone-width. You get the same video, transcript, notes and Fire Score.
