Extension Fixes

Fix "This Extension Is No Longer Supported" in Chrome

Quick Answer

Chrome shows this message when an extension uses Manifest V2 APIs that Chrome has deprecated. You cannot re-enable the old extension, but you can export settings, check for MV3 updates, and find alternatives. Most popular extensions have MV3-compatible replacements available.

Why This Happens

  • The extension relies on Manifest V2, which Chrome has fully deprecated in Chrome 138.
  • The extension was removed from the Chrome Web Store for policy violations.
  • The developer stopped maintaining the extension and it became incompatible with updates.
  • Chrome proactively disabled the extension due to detected security concerns.
  • The extension is incompatible with your specific Chrome version.

What You Can Do

Search for the extension name in the Chrome Web Store for its current status.

Check Extension Fixes for alternatives to common affected extensions.

Look for official MV3 versions or community-maintained forks.

Export your extension settings if still accessible before removing it.

Consider alternative browsers like Firefox if you need specific extension functionality.

Contact the extension developer to inquire about MV3 updates.

Related Extensions

Proxy SwitchyOmega

Proxy Manager

Affected by MV2

Proxy SwitchyOmega stopped working in Chrome because Chrome 138 fully disabled Manifest V2 extensions. The closest migration path is ZeroOmega, a community fork designed for Manifest V3. FoxyProxy is another established option with advanced proxy management features. Both are available on the Chrome Web Store.

uBlock Origin

Content Blocker

Affected by MV2

Classic uBlock Origin stopped working in Chrome 138+ because Chrome disabled Manifest V2 extensions. For many Chrome users, uBlock Origin Lite is the closest MV3-compatible option from the same developer, but it does not replicate every feature of the original extension. Firefox remains a practical option for users who need full classic uBlock Origin functionality, since Firefox still supports MV2 extensions. Avoid installing random CRX copies of classic uBlock Origin from unofficial sources, because modified extensions can create privacy and security risks. The MV3-compatible ad blocker space is actively developed, and other options like AdGuard AdBlocker and Adblock Plus are available in the Chrome Web Store.

Great Suspender

Tab Management

Removed

The original Great Suspender was removed from the Chrome Web Store after a malicious version incident in 2021, and Chrome proactively disabled it for installed users. Users should avoid reinstalling old CRX copies from mirror sites because modified versions can contain unwanted code. For most Chrome users, Chrome Memory Saver is the simplest built-in replacement for tab suspension. Auto Tab Discard is a practical extension alternative for automatic tab unloading, while OneTab is better for manual tab consolidation and Workona is more focused on workspace management. The best option depends on whether you want automatic suspension, simple memory savings, or session organization.

What Not to Do

  • Do not download CRX files from unofficial download sites.
  • Do not install extensions with similar names assuming they are successors.
  • Do not disable Chrome security features to force-install unsupported extensions.
  • Do not give excessive permissions to unknown replacement extensions.
  • Do not assume an extension is safe just because it appears legitimate.
