BEST Great Suspender Alternative in 2026 (MV3, Tested)

Key takeaways

• The original Great Suspender was removed from Chrome Web Store for malware in 2021. Its MV3 forks still work but rely on volunteers.
• Forks show a custom suspension page. chrome.tabs.discard() suspends invisibly and never breaks the back button.
• Active maintenance matters: Chrome ships every 4 weeks, and a fork unupdated for 12 months accumulates silent failures.

If you used The Great Suspender for years and are looking for a tab suspender that works on current Chrome versions, this page covers what happened to the original, the state of its forks, and how SuperchargePerformance compares as a replacement.

What Happened to The Great Suspender

The Great Suspender was trusted by over 2 million Chrome users (Chrome Web Store, pre-removal). In late 2020, the original developer sold it to an unknown buyer. The new owner introduced malware — silently collecting user data and executing remote code. Google removed it from the Chrome Web Store shortly after.

Community forks emerged to fill the gap. The most notable are The Marvellous Suspender and Great Suspender Reloaded. Both removed the malicious code and have since migrated to MV3 — Chrome disabled MV2 for standard users at Chrome 138 in mid-2025.

The Great Suspender Forks in 2026

Chrome disabled Manifest V2 extensions for standard users beginning with Chrome 138. The original Great Suspender was removed for malware and never returned. The forks have continued:

How MV3 Tab Suspension Works

SuperchargePerformance uses chrome.tabs.discard(), Chrome’s native tab lifecycle API. This differs from The Great Suspender’s approach in one important way: instead of replacing the tab’s content with a custom suspension page, the discard API makes suspension invisible. The tab stays in the tab bar with its favicon and title. Clicking it reloads the page naturally. There is no custom suspension screen to navigate around, and the back button is unaffected.

The Great Suspender’s custom suspension page had a few practical drawbacks worth knowing about. It broke the browser back button in some configurations — the suspension page itself became a history entry, so pressing back would navigate to another suspended screen rather than the previous site. Scroll position was also lost, meaning tabs that reloaded from a suspension page always opened at the top. And there was a visible interruption: a custom “Tab Suspended” page shown briefly before the real content loaded. Chrome’s discard API has none of these issues. The tab memory drops to near zero, clicking the tab triggers a normal reload, and there is no custom screen in between.

Feature Comparison

Three Reasons to Switch from a Great Suspender Fork

1. Maintenance and update cadence. The Marvellous Suspender (v8.1.3, Dec 2025) and Great Suspender Reloaded are both on MV3 and functional. But volunteer-maintained forks update on a best-effort schedule. SuperchargePerformance is actively maintained on MV3 with regular updates.

2. Maintenance uncertainty. Chrome ships a new version every four weeks. A volunteer-maintained extension that hasn’t been updated in 12+ months is quietly accumulating silent failures — you often won’t know until something stops working.

3. The ownership history. The 2020 compromise is worth remembering. Forks removed the malicious code, but the original extension was sold to an unknown buyer who weaponized it against millions of users. That risk doesn’t disappear because a fork cleaned up the code.

What Stays the Same

The core tab suspension behavior from The Great Suspender works identically in SuperchargePerformance:

• Inactive tabs have their memory freed
• Tabs playing audio are never suspended (checks tab.audible)
• Pinned tabs are protected
• Tabs with unsaved form inputs are protected
• Per-site whitelist to exclude domains from suspension
• Configurable inactivity timers (5 or 15 min on free tier, custom timer on PRO) (verified March 2026)

Everything that was familiar is present, with the addition of ad blocking, memory metrics, and a popup dashboard showing total RAM saved.

What Happened to The Marvellous Suspender

The Marvellous Suspender forked from the original after the malware incident and has a significant user base. The maintainer migrated to MV3 — as of March 2026, the stable release is v8.1.3 (updated December 2025) on the Chrome Web Store. The project is volunteer-maintained by gioxx. It uses a custom suspension page rather than Chrome’s native chrome.tabs.discard() API.

Trust and Security

The Great Suspender’s 2020 compromise is an object lesson in extension ownership risk. Popular free extensions with no business model can be sold to unknown buyers who then monetize the user base through silent data collection or remote code execution. It happened to 2 million users who had no idea.

SuperchargePerformance has a clear business model: an optional PRO tier. That removes the incentive to monetize through user data. All code runs locally. There are zero outbound network requests, verified from the codebase. No remote code loading, no analytics, no data transmission to any server.

For volunteer-maintained forks, the code is open source and the malicious code was removed. But open-source code can change between releases, and auditing a fork’s latest commit is not something most users do.

Bottom Line

The Great Suspender is gone, and most of its forks don’t run on current Chrome. SuperchargePerformance offers the same tab suspension behavior — tabs stay visible, memory gets freed, audible tabs are protected — on a stable MV3 architecture with active maintenance. The ad blocking and memory dashboard are additions the original never had.
