What's the best Android app for syncing bookmarks and passwords securely across mobile and desktop?

Firefox Fast & Private Browser is designed for users who prioritize privacy and seamless cross-device browsing. Its core strength lies in Firefox Sync, which uses end-to-end encryption to securely transfer bookmarks, passwords, browsing history, and open tabs between Android devices and desktops like Windows or macOS. This ensures that sensitive data, such as login credentials stored in the built-in Lockwise password manager, remains protected from interception. For real-world use, professionals or students switching between devices can instantly access saved research or work materials without manual transfers. The app also supports extensions, such as uBlock Origin, to block ads and trackers, enhancing privacy further. However, some user reviews indicate occasional frustrations with bookmark management, like difficulties in custom ordering, which can be a minor annoyance for power users organizing large collections. Despite this, the synchronization is reliable and works quietly in the background. Users report that the seamless experience reduces friction in daily browsing, making it a solid choice for those invested in the Firefox ecosystem or seeking an alternative to browsers with less transparent data practices. Overall, it balances robust sync capabilities with a commitment to user privacy, though interface refinements could improve usability.
