Both Firefox and Opera are compatible across every platform including Windows, Mac, Linux, Android and iOS. Firefox account holders can easily sync their bookmarks, passwords, open tabs, and browsing history across all their signed into devices. The same is true for Opera users with an account. However, many sites, especially old sites that haven’t been updated in years, block the latest version of Opera entirely. So if visiting places like your Ex’s old blog is important, take heed, you may not be able to access some of the dustier corners of the internet if you use Opera.
Firefox 和 Opera 兼容于以下所有平台，包括 Windows、Mac、Linux、Android 和 iOS。 Firefox 账户持有者可以在所有已登录的设备上轻松同步其书签、密码、打开的标签页和浏览历史，拥有账户的 Opera 用户也能做到。但是，许多网站（尤其是多年未更新的老网站）完全屏蔽了 Opera 的最新版本。因此，如果您有一些像往日伙伴的旧博客等重要等网站要访问，那就要注意了。如果您使用 Opera，很可能无法访问互联网上的一些角落。
