The Great Suspender Alternative — Best Tab Suspenders After the Malware Incident

If you have used Chrome for any length of time with multiple tabs open, you have probably noticed your browser consuming gigabytes of RAM and your computer slowing to a crawl. For years, The Great Suspender was the go-to solution for millions of users seeking to manage their tab overload. But in early 2021, everything changed. Google removed The Great Suspender from the Chrome Web Store after a disturbing discovery that shook the browser extension ecosystem: the beloved extension had been sold, acquired, and injected with malware. This incident left millions of users searching for safe, reliable alternatives—and sparked an important conversation about extension security, trust, and the future of browser productivity tools.

This comprehensive guide explores what happened to The Great Suspender, why tab suspenders remain essential for browser performance, and detailed reviews of the best alternatives available in 2025. Whether you are a power user with dozens of tabs open or simply looking to extend your laptop’s battery life, you will find the information you need to make an informed choice about which tab suspension tool is right for you.

What Happened to The Great Suspender

The Great Suspender began as an open-source project created by Dean Oemcke in 2010. For over a decade, it served as one of the most popular Chrome extensions, helping users manage browser memory by suspending inactive tabs. The extension worked by “freezing” tabs that had not been used for a configurable period, releasing the memory they consumed while preserving their place for quick resumption. Millions of users relied on it to keep their browsers running smoothly, and it maintained a reputation as a trustworthy, lightweight tool.

In 2020, Dean Oemcke sold The Great Suspender to a third-party buyer. This transaction, which involved transferring ownership of a popular extension with millions of users, would prove to be a critical mistake. The new owners, operating under the entity “giantsys,” made changes to the extension that introduced concerning behavior. Version 7.1.8 of The Great Suspender, released in January 2021, was found to include code that attempted to exfiltrate user browsing data and inject advertisements into web pages.

The malicious behavior included making external network requests to track user activity and attempting to manipulate web page content for revenue generation. These actions violated Chrome Web Store policies and fundamentally betrayed the trust that users had placed in the extension. When security researchers and users discovered the malware injection, the backlash was swift and severe.

Google responded by removing The Great Suspender from the Chrome Web Store in January 2021. Users who had the extension installed began receiving warnings, and the extension was automatically disabled for many users. The incident became a landmark case in the ongoing debate about browser extension security and the risks associated with popular tools changing ownership.

The Great Suspender story serves as a cautionary tale about the importance of verifying extension provenance, understanding who maintains the tools you trust, and recognizing the potential risks when ownership changes. For users who had relied on The Great Suspender, the immediate need was finding a safe, reliable alternative that could provide the same memory management benefits without the security concerns.

Why Tab Suspenders Matter

Modern web browsing has evolved dramatically, and with it, the demands placed on browser resources. Today’s websites are complex applications loaded with JavaScript frameworks, multimedia content, tracking scripts, and interactive elements. A single tab can consume anywhere from 50MB to 500MB of RAM, and when you have dozens of tabs open—as many power users do—the cumulative memory consumption can quickly overwhelm your system.

Tab suspenders address this problem by temporarily “suspending” or “discarding” inactive tabs. When a tab is suspended, Chrome releases the memory it was using while saving a lightweight snapshot of the page. When you return to that tab, Chrome quickly restores it, often by reloading only the visible portion of the page while fetching the rest in the background. This approach can reduce memory usage by 50-90% for users with many open tabs.

The benefits extend beyond memory management. For laptop users, reduced memory usage translates to longer battery life, as your computer does not need to manage as much active data. Suspended tabs also reduce CPU usage, which can make your computer quieter and cooler. For users with limited RAM or older hardware, tab suspenders can mean the difference between a usable browser and one that constantly freezes or crashes.

The Great Suspender malware incident highlighted another important aspect of tab suspenders: the trust equation. Because tab suspenders have access to your browsing activity—they need to know when tabs are active or inactive to function—they represent a significant security consideration. Choosing a tab suspender from a trusted developer, with transparent practices and minimal permissions, is essential for protecting your privacy and security.

Tab Suspender Pro: The Featured Safe Alternative

Tab Suspender Pro has emerged as the leading alternative to The Great Suspender, offering a comprehensive set of features with a strong emphasis on security and privacy. Developed with the lessons learned from The Great Suspender incident in mind, Tab Suspender Pro was built from the ground up with security as a core principle.

The extension operates on Manifest V3, the latest version of Chrome’s extension architecture, which provides improved security controls and more restricted access to user data. Unlike The Great Suspender, which required broad permissions to function, Tab Suspender Pro requests only the permissions essential to its core functionality. This minimal permissions approach reduces the potential attack surface and makes it easier for security-conscious users to audit the extension’s behavior.

Tab Suspender Pro offers flexible suspension triggers. You can configure tabs to suspend after a specified period of inactivity, immediately when you close a tab, or never for pinned tabs. The extension also supports whitelisting websites that should never be suspended, such as webmail services or streaming platforms where interruptions are problematic. These configuration options give you fine-grained control over how and when tabs are suspended.

Privacy is a cornerstone of Tab Suspender Pro’s design. The extension does not collect any user data, does not make external network requests beyond what is necessary for its core functionality, and does not include any advertising or tracking code. The developer has published a clear privacy policy explaining exactly what data the extension accesses and how it is handled. For users who were burned by The Great Suspender incident, this transparent approach to privacy provides reassurance that their data is safe.

The extension also includes quality-of-life features that improve the user experience. Tab Suspender Pro displays a visual indicator on suspended tabs, making it easy to see which tabs are active and which are suspended. You can configure the appearance of suspended tabs, including using a custom screenshot or a simple placeholder. The extension supports keyboard shortcuts for quickly suspending or resuming tabs, which power users will appreciate.

For users migrating from The Great Suspender, Tab Suspender Pro offers an import feature that can help you bring over your settings and whitelists. While you cannot directly import data from the original malicious version, the extension provides guidance on reconfiguring your settings to match your previous setup.

The Marvellous Suspender: The Open Source Fork

Following The Great Suspender incident, the open-source community responded by creating The Marvellous Suspender, a fork of the original extension’s code designed to maintain the functionality users loved while removing any malicious components and improving security.

The Marvellous Suspender is developed as a truly open-source project. The source code is publicly available on GitHub, allowing security researchers and concerned users to inspect the code for any concerning behavior. This transparency is a significant advantage over proprietary alternatives, as anyone can verify that the extension does what it claims to do without secretly collecting data or injecting advertisements.

The extension retains most of the features that made The Great Suspender popular. You can configure automatic suspension timing, manage whitelists of sites that should never suspend, and choose how suspended tabs appear. The Marvellous Suspender also includes some improvements over the original, such as better support for modern web applications that rely on background processes.

However, there are some considerations to keep in mind. The Marvellous Suspender currently runs on Manifest V2, which Google is gradually phasing out in favor of Manifest V3. While the extension remains functional at the time of writing, users should be aware that future Chrome updates may require the developers to migrate to Manifest V3, which could introduce changes or limitations. The development team has indicated they are working on a Manifest V3 version, but the timeline is uncertain.

For users who prioritize open-source transparency and community oversight, The Marvellous Suspender is an excellent choice. It provides the familiar interface and functionality of The Great Suspender without the malware concerns, and the active community around the project helps ensure ongoing development and security maintenance.

Auto Tab Discard: Chrome’s Native Solution

Chrome includes built-in tab discarding functionality that provides a no-extension-required option for managing tab memory. When Chrome detects that system memory is running low, it automatically discards inactive tabs, releasing their memory while preserving their place. This behavior is built into Chrome and requires no additional installation.

Auto Tab Discard is an extension that provides more control over Chrome’s native discarding functionality. Rather than relying on Chrome’s automatic behavior, you can manually configure which tabs should be discarded and when. The extension allows you to set up rules based on tab URL patterns, domain names, or manual selection, giving you more granular control than Chrome’s default behavior provides.

The advantage of Auto Tab Discard is its minimal footprint. Because it builds on Chrome’s native discarding mechanism, it requires fewer permissions and less code than fully-featured tab suspenders. This simplicity reduces the attack surface and makes the extension easier to trust. However, it also means that Auto Tab Discard offers fewer features than alternatives like Tab Suspender Pro.

For users who prefer a lightweight solution that relies on Chrome’s built-in functionality, Auto Tab Discard provides a useful middle ground. It gives you some control over tab discarding without requiring you to trust a complex extension with broad permissions.

Workona: Beyond Simple Tab Suspension

Workona takes a fundamentally different approach to tab management than simple tab suspenders. Rather than focusing solely on memory management, Workona provides a comprehensive workspace system that helps you organize projects, research topics, and research areas across multiple tabs.

With Workona, you create workspaces that group related tabs together. When you switch between workspaces, Workona can save your current tab state and restore a different set of tabs. This approach is particularly useful for users who work on multiple projects simultaneously and need to quickly switch between different sets of resources without losing their place.

Workona includes tab suspension as part of its feature set. You can configure workspaces to suspend tabs when you switch away, helping manage memory usage while maintaining your organized workflow. The extension also offers features like tab sharing, cloud sync across devices, and a searchable history of your tabs and workspaces.

The trade-off with Workona is complexity. While it provides powerful organization features, it requires more setup and configuration than simple tab suspenders. It also requires more permissions to function, as it needs access to your tab and browsing data to provide its workspace functionality. For users who need sophisticated tab organization, Workona is an excellent choice, but those seeking simple memory management may find it overkill.

Toby: Visual Tab Management

Toby offers another approach to tab management, emphasizing visual organization and quick access to your tab collections. Rather than relying on automatic suspension, Toby provides a dashboard-style interface that displays all your open tabs in a visual format, making it easy to see what you have open and quickly navigate to specific tabs.

Toby organizes tabs into collections, which you can create and name based on your projects or interests. When you open Toby, you see your collections displayed as visual cards, each showing the favicons and titles of tabs within that collection. This visual approach makes it easy to find what you are looking for without scrolling through Chrome’s tab bar.

Like Workona, Toby includes tab suspension features that you can enable for specific collections. You can configure collections to suspend tabs when they become inactive, helping manage memory while keeping your organized structure intact. Toby also supports syncing your collections across devices, so you can maintain your tab organization whether you are on your work computer or personal device.

For users who struggle with tab overload and benefit from visual organization, Toby provides a compelling solution. However, it requires more setup and ongoing management than automatic tab suspenders, and the visual interface may not appeal to users who prefer a minimal, unobtrusive approach.

Comparison Table: Tab Suspension Alternatives

How to Evaluate Extension Safety

The Great Suspender incident taught the browser extension community an important lesson: even popular, long-established extensions can become dangerous when ownership changes. Before installing any extension, especially one that requires significant permissions, you should take steps to evaluate its safety and trustworthiness.

Start by examining the permissions the extension requests. Extensions that ask for excessive permissions—access to all websites, ability to read and modify data, access to browsing history—should give you pause. Ask yourself whether the requested permissions are necessary for the extension’s core functionality. A simple tab suspender should not need access to read all your browsing data or modify web page content.

Research the developer or organization behind the extension. Look for information about who maintains the extension, how long it has been available, and whether the developer has a track record of producing secure, privacy-respecting software. Extensions that are open source provide an additional layer of transparency, as security researchers can audit the code for any concerning behavior.

Read the extension’s privacy policy carefully. Legitimate extensions should have a clear privacy policy explaining what data they collect, how they use it, and whether they share it with third parties. Be wary of extensions that have no privacy policy or whose policies are vague or overly broad.

Check user reviews and look for any reports of suspicious behavior. The Great Suspender incident generated significant discussion in the security community, and many users reported concerning behavior before the extension was removed. Look for patterns in reviews that might indicate problems.

Finally, consider the extension’s update history. Extensions that are regularly updated are more likely to be actively maintained and fixed when security issues are discovered. Extensions that have not been updated in years may be abandoned and could pose security risks.

Migrating Data from The Great Suspender

If you were a user of The Great Suspender before it was removed, you will need to manually recreate your settings in your chosen alternative. Unfortunately, due to the malicious changes made to The Great Suspender, you cannot safely import your settings directly from the compromised version.

Start by documenting your previous settings: which sites were whitelisted, what suspension timing you used, and how suspended tabs appeared. You will need to reconfigure these settings in your new extension, but the process is straightforward for most alternatives.

Tab Suspender Pro and other alternatives provide configuration options that mirror The Great Suspender’s functionality, so you should be able to recreate your setup without significant difficulty. Take this opportunity to review your whitelisted sites and remove any that you no longer need, simplifying your configuration.

Building Trust as an Extension Developer

For developers creating browser extensions, the The Great Suspender incident offers important lessons about building and maintaining user trust. Users are increasingly security-conscious, and demonstrating that your extension is safe and respectful of their privacy can be a significant competitive advantage.

Transparency is foundational. Publish your source code if possible, or at minimum provide detailed explanations of how your extension works. Clear, accessible documentation helps users understand what your extension does and why it needs the permissions it requests.

Minimal permissions should be a design principle. Request only the permissions absolutely necessary for your extension’s functionality, and be prepared to explain why each permission is needed. Users and reviewers are more likely to trust extensions that demonstrate restraint in their permission requests.

Publish a clear, comprehensive privacy policy. Explain what data your extension accesses, how it uses that data, and whether it shares anything with third parties. If your extension does not collect any user data, say so explicitly.

Maintain active development and communication with your users. Regular updates demonstrate that your extension is actively maintained, and responsive support helps build confidence that issues will be addressed. If security vulnerabilities are discovered, respond quickly and transparently.

Consider independent security audits. Having your code audited by third-party security researchers can provide additional assurance to users that your extension is safe. Publish the results of these audits when possible.

Finally, be thoughtful about monetization. Users are suspicious of extensions that collect data for advertising or that include aggressive advertising within the extension itself. If you need to monetize your extension, consider premium features, donations, or other approaches that do not involve harvesting user data.

Conclusion

The Great Suspender malware incident marked a turning point in how users and developers think about browser extension security. While the incident was unfortunate, it spawned a new generation of tab management tools that prioritize user privacy and transparency. Whether you choose Tab Suspender Pro for its modern Manifest V3 architecture and privacy-focused design, The Marvellous Suspender for its open-source transparency, or another alternative that fits your workflow, you have more options than ever for managing your browser tabs safely and effectively.

For most users, Tab Suspender Pro represents the best balance of features, security, and ease of use. Its minimal permissions, clear privacy policy, and active development make it a trustworthy choice that carries forward the spirit of what made The Great Suspender popular while addressing the security concerns that led to its downfall.

Whatever alternative you choose, take the time to configure it properly and understand its permission requirements. Your browser is your gateway to the internet, and the extensions you install have significant access to your activity. By choosing wisely and staying informed, you can enjoy the memory management benefits of tab suspenders without compromising your security or privacy.
