This Extension Was Turned Off Because It Is No Longer Supported

Chrome shows "This extension was turned off because it is no longer supported" when an extension has been automatically disabled. This happens when the extension uses deprecated APIs, was removed from the Web Store, or violates current Chrome policies. You generally cannot re-enable it — check the Chrome Web Store for an MV3 update or find a maintained alternative.

Cannot Install Extension Because It Uses an Unsupported Manifest Version

Chrome shows an unsupported manifest version error when an extension package uses an older extension format that modern Chrome no longer accepts, most commonly Manifest V2. In current Chrome versions, ordinary users generally cannot fix this by changing a simple setting. Reinstalling the same extension, downloading random CRX files, or disabling security protections can create privacy and malware risks. The safer path is to check whether the developer provides a Manifest V3 version, install a maintained alternative from the Chrome Web Store, or use a browser that still supports the extension you need.

Proxy SwitchyOmega

Proxy Manager

uBlock Origin

Content Blocker

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

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.

Violentmonkey

Script Manager

Violentmonkey is an open-source userscript manager used to run custom browser scripts on websites you visit. If you need a Violentmonkey alternative for Chrome, Tampermonkey is the most widely known option, while Violentmonkey remains a practical choice for users who prefer an open-source workflow. The right choice depends on script compatibility, permission expectations, browser support, and how much control you want over imported scripts. Userscript managers can run powerful code on pages you visit, so avoid random script mirrors, review script permissions, and only install scripts from sources you trust. The Violentmonkey page on Extension Fixes compares both options with migration steps, safety notes, and a full comparison table.

FoxyProxy

Proxy Manager

FoxyProxy remains a practical Chrome proxy manager for users who need multiple proxy profiles, pattern-based switching, and quick control over browser proxy settings.

FoxyProxy is a better fit when you want an established proxy manager with long-running Chrome and Firefox support. The best choice depends on whether you need SwitchyOmega-style rules, FoxyProxy-style profiles, or a simpler one-click proxy switcher.

The MV3-compatible version developed by the same author is uBlock Origin Lite, available as a free Chrome uBlock Origin Lite extension in the Chrome Web Store. While not a complete one-to-one replacement due to MV3 limitations, uBlock Origin Lite provides strong ad blocking for most users who rely on filter lists.
