Download Xmarks – Secure Firefox Bookmark Sync

Overview

Xmarks (formerly known as Foxmarks) is a dedicated Firefox extension that lets you synchronize bookmarks, open tabs, and browsing history across any number of computers where Firefox runs. Whether you flip between a Windows workstation at the office and a macOS laptop at home, Xmarks keeps your favorite links instantly available. The service requires a simple user account that is created through an intuitive configuration wizard during the first launch, and all data transmission is encrypted, ensuring that your bookmark collection remains private and secure.

In addition to its core syncing capability, Xmarks adds a handy icon to the URL bar that opens a dropdown panel displaying information about the current site and a curated list of similar sites, turning your browser into a mini discovery engine. While Xmarks no longer supports password synchronization, it integrates smoothly with complementary password managers like LastPass, allowing you to maintain a complete, cross‑device browsing experience. The extension operates silently in the background, automatically updating your data at browser shutdown or at intervals you define, and it can even be configured to run through your own server for maximum control over where your information is stored.

Overall, Xmarks offers a fast, reliable, and feature‑rich solution for anyone who relies on Firefox across multiple platforms and wants a hassle‑free way to keep their web navigation assets synchronized.

Installation & Usage Instructions

Downloading and Installing Xmarks

To begin, navigate to the official Xmarks download page or the Firefox Add‑Ons Marketplace. Click the “Add to Firefox” button, and a confirmation dialog will appear. Accept the permissions request, and Firefox will automatically download and install the extension. After installation, the Xmarks icon appears to the right of the address bar, indicating that the add‑on is active.

Creating Your Xmarks Account

On first launch, Xmarks opens a configuration wizard. You will be prompted to enter an email address and create a strong password. The wizard walks you through optional steps such as choosing a default sync profile and deciding whether to enable automatic sync at shutdown. All account data is stored securely on Xmarks’ servers unless you opt for the self‑hosted mode.

Syncing Your Bookmarks

Once logged in, Xmarks automatically begins the initial sync. This process scans your existing Firefox bookmarks, uploads them to the cloud, and then pulls any bookmarks that may already exist on other devices linked to the same account. The sync typically completes within a few seconds, depending on the size of your collection. You can manually trigger a sync at any time by clicking the Xmarks icon and selecting “Sync Now.”

Managing Tabs and History

To extend synchronization beyond bookmarks, open the Xmarks settings panel and enable “Sync Open Tabs” and “Sync Browsing History.” When enabled, any tabs you close on one machine will reappear as a “Recent Tabs” list on your other devices. History sync works similarly, merging your browsing records so you can search for previously visited pages from any computer.

Advanced Options

Power users can create multiple sync profiles by navigating to the “Profiles” tab within the Xmarks dashboard. This feature is ideal for separating work‑related bookmarks from personal collections. Additionally, if you prefer not to store data on Xmarks’ servers, select the “Self‑Hosted” option and provide the URL of your own sync server. Detailed instructions for setting up a self‑hosted server are available on the Xmarks support site.

Troubleshooting Common Issues

If sync appears stalled, ensure that your internet connection is stable and that no firewall rules block Xmarks traffic. You can also reset the sync by logging out of your account, clearing the local cache (found under “Advanced Settings”), and then signing back in. This forces a fresh sync and often resolves minor inconsistencies.

Compatibility, Pros & Cons

Supported Operating Systems

Xmarks works with any operating system that supports the Firefox browser, including Windows 10/11, macOS 10.13 and later, Linux distributions (Ubuntu, Fedora, etc.), and even Firefox for Android (limited to bookmark sync). Because the extension runs inside Firefox, you do not need separate installers for each platform; the same add‑on package is used across all supported environments.
