Fix "This Extension Is No Longer Supported" in Chrome
Chrome shows "This extension is no longer supported" when an extension uses outdated APIs, was removed from the Web Store, or is incompatible with your Chrome version. The safest approach is to find a maintained replacement from the Chrome Web Store. Avoid downloading old copies from unofficial sources.
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.
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.

Proxy SwitchyOmega
Proxy Manager
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
Classic uBlock Origin stopped working in Chrome 138 because Chrome disabled Manifest V2 extensions. The official MV3 replacement is uBlock Origin Lite, developed by the same author. For full feature parity, Firefox with classic uBlock Origin remains an option. Other MV3-compatible ad blockers like AdGuard and Adblock Plus are also available.
Great Suspender
Tab Management
The original Great Suspender was removed from the Chrome Web Store and disabled by Google in 2021 due to malware-related concerns. Do not install CRX copies of this extension from unofficial sources. Use Chrome built-in Memory Saver or alternatives like Auto Tab Discard for tab suspension needs.
