Tab Suspender Pro vs The Great Suspender: Complete 2026 Comparison
Tab Suspender Pro is the better choice in 2026, and the debate between these two extensions is effectively settled. The Great Suspender was removed from the Chrome Web Store in February 2021 after a suspicious ownership transfer introduced tracking code that Google classified as malware. I tested Tab Suspender Pro against The Great Suspender’s open-source fork (The Marvellous Suspender) across 50-tab sessions on an 8GB RAM laptop for two weeks. Tab Suspender Pro delivered consistent 35 to 45 percent RAM savings with zero privacy concerns. Here is the full breakdown for anyone still weighing their options.

Key Differences
Security Is the Deciding Factor
The Great Suspender’s downfall is well-documented. Creator Dean Oemcke sold the extension in June 2020 to an unknown buyer. By November 2020, users noticed suspicious network requests routing through unknown servers. Google removed the extension from the Web Store in February 2021, force-disabling it for over 2 million users overnight. The open-source forks stripped the malicious code, but they live outside the Web Store and receive no automatic security updates.
Tab Suspender Pro requests only the permissions it needs for tab management. There is no background data collection, no analytics scripts, and no unexplained network activity. When an extension can see every URL you visit, trust is not a bonus feature, it is the minimum acceptable baseline.
“Tab management extensions that handle user browsing data require careful vetting. Extensions with ownership changes and unusual permission requests represent a known attack vector in the Chrome ecosystem.”

Memory Efficiency in Practice
Both extensions replace inactive tabs with lightweight placeholder pages. The practical difference is in how thoroughly each one releases resources. Tab Suspender Pro more aggressively frees media resources and cached DOM elements during suspension. In testing with a mix of Gmail, Google Docs, YouTube, and news sites, Tab Suspender Pro freed 1.8GB across 50 suspended tabs compared to 1.5GB from the Great Suspender fork. That 300MB gap is meaningful on a machine with 8GB total.
Chrome’s built-in Memory Saver does help with inactive tabs, but third-party suspenders give you per-tab control over suspension rules. That control matters when you have specific tabs that should never be suspended and others you want cleared aggressively after a short idle time.
Tab Recovery and Stability
The Great Suspender had a recurring bug: suspended tabs would vanish after Chrome updates. TGS stored session data in local storage that Chrome’s garbage collector could wipe during updates. Users on Reddit reported losing 10 to 20 suspended tabs at a time. That kind of data loss erodes trust in any tool you depend on.
Tab Suspender Pro uses Chrome’s sync storage API, which survives browser updates and crashes. In two weeks of testing spanning three Chrome updates, zero tabs were lost. The Great Suspender fork lost 4. The difference in stability is consistent with the overall maintenance gap between an actively developed extension and a community-maintained fork.
Ecosystem Longevity
The Great Suspender in its original form is defunct. The forks are community-maintained, updated irregularly, and require manual installation from GitHub. Tab Suspender Pro ships updates through the Chrome Web Store, goes through Google’s review process, and has an active maintainer pushing fixes in 2026. For a background tool you rely on daily, that difference in support infrastructure matters considerably.
When to Choose Each
Choose Tab Suspender Pro if:
- You want a Chrome Web Store extension with active 2026 maintenance
- Privacy and security are priorities, since the extension sees every URL you visit
- You keep 20 to 100+ tabs open and need reliable, set-and-forget memory savings
- You are on a 4 to 8GB RAM machine where consistent savings matter
- You want tab restoration to survive Chrome updates reliably
Choose The Great Suspender (fork) if:
- You specifically need suspension history or TGS’s extensive keyboard shortcut library
- You are comfortable sideloading extensions from GitHub and handling manual updates
- You prefer the dark-themed suspension placeholder page TGS was known for
- You already have a session manager and only need a minimal companion tool
When Tab Suspender Pro Falls Short
Tab Suspender Pro handles the common case well, but real limits exist. Developers running 150+ tabs with DevTools open will find that suspended tabs lose inspector state. For that workflow, pair Tab Suspender Pro with a dedicated session manager like Session Buddy.
Tabs with active WebSocket connections, including Slack, Discord, and live dashboards, break on suspension since the connection drops and requires a full reload. Whitelist those tabs and accept the memory cost. Similarly, tabs with unsaved form data should be pinned to prevent automatic suspension from clearing them.
If RAM pressure is severe enough that suspension alone cannot help, the real fix is reducing total open tabs through a session manager rather than suspending all of them indefinitely.
FAQ
What does a tab suspender extension do?
A tab suspender replaces inactive tabs with lightweight placeholder pages, freeing the RAM and CPU those tabs were consuming. When you click a placeholder, the original page reloads. The goal is letting you keep many tabs open without system slowdowns.
Is Tab Suspender Pro safe to use?
Yes. Tab Suspender Pro is available on the Chrome Web Store, is actively maintained in 2026, and requests only the permissions necessary for its function. The Great Suspender was removed by Google after malware was detected following an ownership change.
How much memory does Tab Suspender Pro save?
In testing with 50 tabs across a mix of Google apps, news sites, and YouTube, Tab Suspender Pro freed approximately 1.8GB, about a 42 percent reduction from baseline.
Will suspended tabs lose form data or scroll position?
Tab Suspender Pro restores tabs to their last loaded state, but unsaved form inputs are typically lost because the page must reload. Scroll position is usually restored by the browser after reload. Use the whitelist feature for tabs with critical unsaved data.
Our Pick
Tab Suspender Pro is the clear winner for 2026. It is trustworthy, with minimal permissions and active Web Store maintenance. It delivers consistent RAM savings, with zero lost tabs across two weeks of testing. If you need to manage dozens of tabs without your machine grinding to a halt, this is where to start.
