# Chrome Update Disables Ad Blockers: Manifest V3 Breaks uBlock Origin, AdBlock Plus in Chrome 150-151

Chrome Update Disables Ad Blockers: Chrome 150 and 151 will disable popular ad blockers like uBlock Origin and AdBlock Plus. Google migrating from Manifest V2 to Manifest V3, removing MV2 flags in 2026. Wind-down started 2024, full MV2 disabled mid-2025.
Google Chrome's next updates will **disable many popular ad blockers** including **uBlock Origin** and **AdBlock Plus** as Google completes the migration from **Manifest V2 to Manifest V3** for Chrome extensions.

**Chrome 150** will remove the "ExtensionManifestV2Disabled" flag (the last workaround to keep MV2 blockers alive), and **Chrome 151** will delete all remaining Manifest V2-related flags, closing the door for MV2-based ad blockers completely.

## Timeline: When This Happens

| Chrome Version | What Happens | Timeline |
| -------------- | ------------ | -------- |
| **Chrome 149** (current) | Last workarounds still available | June 2026 (current) |
| **Chrome 150** | Removes "ExtensionManifestV2Disabled" flag | Late 2026 |
| **Chrome 151** | Removes all MV2 flags: "ExtensionManifestV2Unsupported", "ExtensionManifestV2Availability", "AllowLegacyMV2Extensions" | Early 2027 |

The wind-down **started in 2024**, and by **mid-2025 Chrome disabled Manifest V2 extensions for most users**. Now Google is removing the final escape hatches.

## Which Ad Blockers Will Be Disabled

| Ad Blocker | Status | Why Disabled |
| ---------- | ------ | ------------ |
| **uBlock Origin** | ❌ Will be broken | Uses Manifest V2 |
| **AdBlock Plus** | ❌ Will be broken | Uses Manifest V2 |
| **AdBlock** | ❌ Will be broken | Uses Manifest V2 |
| **MV3-compatible blockers** | ✅ Still work | Use new Manifest V3 |
| **Chrome's built-in ad limiter** | ✅ Still works | Native Chrome feature |

**uBlock Origin** — one of the most trusted and popular ad blockers — quietly breaks on Chrome.

## What's Changing: Manifest V2 to Manifest V3

## Manifest V2 (Old System)

- **More powerful** — ad blockers could access entire web page before loading
- **Better filtering** — could block ads more effectively
- **Used by** — uBlock Origin, AdBlock Plus, AdBlock

## Manifest V3 (New System)

- **Less powerful** — limits what extensions can access
- **Restricted filtering** — can't block all ads effectively
- **Required by** — All new Chrome extensions

Google is **shutting down the older system that strong ad blockers depend on to do their job**.

## Why Google Is Doing This

Google claims Manifest V3 improves:

- **Security** — extensions have less access to sensitive data
- **Performance** — faster extension loading
- **Privacy** — better control over what extensions can see

However, critics argue it's really about:

- **Protecting ad revenue** — Google earns billions from ads
- **Reducing competition** — makes it harder to block ads effectively
- **Controlling extensions** — more control over what extensions can do

## What Happens to Your Ad Blocker

## If You're Using Manifest V2 Ad Blockers:

| Version | Result |
| ------- | ------ |
| **Chrome 149** | Still works (but limited) |
| **Chrome 150** | Breaks completely (flag removed) |
| **Chrome 151** | No way to use MV2 blockers (all flags removed) |

## After Chrome 150:

- **Limited DevTools workaround** remains, but requires manual page element editing each time
- **Not suitable for daily use** — too cumbersome

## After Chrome 151:

- **No workaround** — Manifest V2 ad blockers completely gone
- Only MV3-compatible blockers work

## Alternatives to Check

## Manifest V3-Compatible Ad Blockers:

- **AdGuard** (MV3 version)
- **Pocket Ad Block** (MV3)
- **Certain versions of AdBlock** (MV3)

However, **MV3 blockers are significantly less effective** than MV2 blockers due to API restrictions.

## Browser Alternatives:

- **Brave Browser** — built-in ad blocking (no extensions needed)
- **Firefox** — still supports Manifest V2 extensions
- **Safari** — doesn't use Manifest V3

## How to Check Your Current Status

- **Open Chrome** → Click puzzle icon (extensions)
- **Manage extensions** → Find your ad blocker
- **Check manifest version** — Look for "Manifest V2" or "Manifest V3"
- **If V2** — It will break in Chrome 150-151

## What You Should Do

## If You Want to Keep Blocking Ads:

| Option | Action |
| ------ | ------ |
| **Switch to Firefox** | Still supports Manifest V2 |
| **Use Brave Browser** | Built-in ad blocking |
| **Find MV3 ad blocker** | Less effective but works |
| **Use Chrome's built-in limiter** | Blocks intrusive ads only |
| **Wait for uBlock Origin MV3** | May come in future |

## If You Don't Care About Ad Blocking:

- Just let Chrome update automatically
- Your ad blocker will disappear

## The Bottom Line

Chrome 150 and 151 will completely disable popular Manifest V2 ad blockers like **uBlock Origin** and **AdBlock Plus** by removing the last flags that allowed MV2 extensions to work. The transition from Manifest V2 to Manifest V3 started in 2024, with full MV2 disabled for most users by mid-2025. Chrome 149 (current version) still has workarounds, but Chrome 150 removes the "ExtensionManifestV2Disabled" flag, and Chrome 151 removes all remaining MV2 flags. Strong ad blockers that depend on Manifest V2 will break completely, leaving users with less effective MV3 alternatives or browser switches to Firefox/Brave.
