Trezor Bridge in 2025: Does It Still Work with Modern Browsers?

For years, Trezor Bridge has been an essential tool for connecting Trezor hardware wallets to web browsers, ensuring seamless communication for secure crypto transactions. However, recent updates in Chrome and other major browsers have introduced changes in how devices interact with web applications, leaving many users wondering if Trezor Bridge is still supported.

The problem? Some browsers are phasing out older connection methods in favor of modern APIs like WebUSB, which can lead to compatibility issues. The solution? Understanding exactly where Trezor Bridge stands today and what options you have moving forward. In this article, we’ll explore the current browser compatibility status, why these changes are happening, and how to adapt your workflow so you can continue using your Trezor without interruptions.

Key Browser Changes Affecting Trezor Bridge Users 

Over the past few years, major browsers like Chrome, Firefox, and Edge have implemented stricter security and device access policies. These updates are designed to protect users from malicious websites, but they’ve also changed how hardware devices—like Trezor wallets—communicate with web applications. Trezor Bridge used to manage this communication by launching a local service that users could access through their browsers. However, recent browser updates have shifted towards newer connection protocols such as WebUSB and WebHID, which allow direct communication between the browser and hardware without requiring additional software.

While this change improves speed and reduces dependency on background apps, it also means that in some cases, Trezor Bridge may no longer be necessary—or fully supported—on certain browsers. For instance, Chrome now gives preference to WebUSB for device access, which completely avoids Trezor Bridge. Firefox, on the other hand, has been slower to adopt these standards, keeping Bridge more relevant for its users. These evolving browser policies highlight the importance of understanding your browser’s compatibility so you can choose the right connection method for your Trezor device.

Current Trezor Bridge Support Across Major Browsers 

As of 2025, Trezor Bridge is still functional, but its necessity and compatibility vary depending on the browser you use. In Google Chrome (latest versions), the browser now prefers WebUSB for connecting to hardware wallets. This means Trezor Bridge is no longer strictly required for Chrome users, though it can still work as a fallback if WebUSB is unavailable or disabled. Microsoft Edge, built on the same Chromium engine, follows a similar pattern.

In Mozilla Firefox, Trezor Bridge remains the primary connection method since Firefox does not fully support WebUSB. This makes Bridge essential for users who rely on Firefox for Trezor Suite Web or third-party wallet integrations. Safari on macOS currently lacks native WebUSB support as well, meaning Bridge can still be necessary there.

Trezor continues to maintain Bridge updates for Windows, macOS, and Linux to ensure backward compatibility and support for browsers that haven’t fully embraced newer standards. However, given the industry shift toward direct browser-to-device communication, its role is slowly diminishing. Users should check their browser’s latest release notes and Trezor’s official guidance to determine the most reliable connection method for their setup.

Top Alternatives to Trezor Bridge and How They Work 

1. Trezor Suite (Desktop App)

• Trezor Suite Desktop bypasses browser dependency by running as a standalone application, connecting directly to your hardware wallet via USB. This eliminates compatibility issues caused by browser updates, offering a stable, secure environment with full Trezor functionality, regular updates, and built-in protection against malicious websites or phishing attempts.

2. Direct WebUSB Support in Browsers

• WebUSB allows browsers like Chrome and Edge to connect directly to Trezor devices without extra software. Pros: quick setup, no background service needed, and cross-platform convenience. Cons: limited browser support, occasional stability issues, and possible restrictions from strict security policies or enterprise-managed browser environments.

3. Other Third-Party Integrations or Extensions

• Some crypto exchanges, DeFi platforms, and wallet extensions connect directly to Trezor devices via WebUSB or APIs, bypassing Bridge. These solutions can be convenient and fast but rely heavily on the provider’s security standards, may lack full Trezor features, and could be vulnerable if the third-party platform is compromised.

4. Pros and Cons of Switching to Alternative Methods

• Alternatives to Trezor Bridge offer faster setup, reduced software dependencies, and better compatibility with modern browsers. However, they may limit cross-browser functionality, reduce offline access options, or introduce new security concerns. Choosing an alternative should balance convenience with reliability, ensuring long-term device compatibility and maintaining Trezor’s core security benefits.

Security Considerations for Trezor Bridge and Its Alternatives 

When managing cryptocurrency, maintaining security is paramount, and your connection method to the Trezor device plays a critical role. Trezor Bridge offers a controlled, encrypted channel between your wallet and browser, reducing the risk of unauthorized access. However, as browsers move toward direct WebUSB connections, security shifts to the browser’s own safeguards. While WebUSB can be secure when used on trusted sites, it may expose users to phishing risks if permissions are granted to malicious domains.

Third-party integrations add convenience but depend on the platform’s security policies, which may not match Trezor’s standards. Regardless of the method used, always connect your Trezor only to official Trezor Suite or verified partner platforms, keep firmware and software updated, and double-check site URLs before approving transactions. This proactive approach ensures your crypto remains protected against evolving threats.

Step-by-Step: How to Check Your Browser Compatibility 

To verify if your browser supports Trezor Bridge or alternatives like WebUSB, visit the official Trezor Suite Web page with your device connected. The site will automatically detect your browser and suggest the appropriate connection method.

You can also review your browser’s release notes or Trezor’s compatibility documentation for the latest support status. If your browser prompts for WebUSB permissions, it likely supports direct device communication; if not, you may need Trezor Bridge or the Trezor Suite Desktop App for full functionality.

Conclusion

Trezor Bridge remains a useful tool for many users, especially on browsers without full WebUSB support like Firefox and Safari. However, with Chrome and Edge shifting toward direct device communication, its role is gradually decreasing. By understanding your browser’s compatibility and exploring alternatives such as Trezor Suite Desktop, you can ensure seamless, secure access to your hardware wallet.

Regularly updating both your Trezor firmware and connection method will help you adapt to evolving browser technologies while maintaining strong security for your cryptocurrency.
