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.
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.
