SyncMarks
Cross-browser bookmark and tab synchronization through a server operated by the user.
Meet SyncMarks
SyncMarks pairs a browser extension with a self-hosted web application to synchronize bookmarks and open tabs. Each browser profile can use its own configuration, making it possible to separate collections or connect different profiles to different servers.
The publisher describes support across Firefox, Chrome and Edge without requiring a vendor-specific cloud account. Firefox for Android support is an extension capability, not a separate native Android application; server administration remains the user's responsibility.
