The author proposes changes to create a more level playing field and highlights areas where Firefox faces restrictions or limitations. They advocate for updates to App Store policies, support for third-party multi-process applications, JIT support, improved accessibility APIs, Messages integration, importing browser data, setting default browser, origin-based associated domains, browser extension support, and beta testing on iOS. On Android, the author discusses limitations on importing browser data and features launching Chrome instead of the user’s default browser. On Windows, they address setting the default browser, the default browser being set to Edge in certain flows, and some Windows features launching Edge instead of the user’s default browser.
