We live in a digital era where your web browser is more than just a tool—it’s your daily gateway to everything online. But what happens when the browser you trust begins to betray that trust? In 2025, we’re witnessing exactly that. Google Chrome, the most dominant browser in the world, has finally begun its long-threatened war against ad blockers.
This article breaks down everything you need to know about Manifest V3, Google’s changes, their impact on your privacy, and what you can do to fight back.

The Beginning of the End: Manifest V3 Is Here
So, what is all the fuss about? It boils down to something called Manifest V3 (MV3). Google introduced this new extension architecture to replace the more powerful Manifest V2 (MV2) system. MV3 limits how browser extensions can intercept and modify network requests, essentially neutering the functionality of advanced ad blockers like uBlock Origin.
Let’s take a moment to understand the core changes:
- MV2 Allowed: Real-time interception and modification of web requests using
webRequest - MV3 Allows: Only a pre-defined set of rules using
declarativeNetRequest - Impact: Ad blockers can’t dynamically block new, unknown threats or apply complex filtering
Now, Google claims this change improves browser performance and security. But the timing and the scale of the damage make it clear: it’s also about regaining ad revenue lost to effective blocking tools.
Extensions Vanish Overnight: Real User Experiences
If you’ve opened Chrome recently and noticed that your favorite extensions have been disabled or vanished, you’re not alone. Many users on forums like Reddit’s r/chrome are reporting mass extension removals and feature deprecation.
For example, the popular uBlock Origin now shows a greyed-out install button. You simply can’t install it anymore unless you resort to workarounds. Some users have resorted to the lighter version, uBlock Origin Lite, but even that has limitations and doesn’t block all YouTube ads.
“YouTube ads started slipping through. That’s my last straw. Switched to Brave yesterday.” — Chrome User on Reddit
Workaround: How to Re-Enable Manifest V2 Extensions (Temporarily)
Still want to use uBlock Origin in Chrome? There’s a workaround, at least for now.
Let’s go through it together:
- Open Chrome and navigate to
chrome://flags - Look for Temporarily unexpire M136 flags or M137 flags depending on your version
- Enable it
- Search for “Extension Manifest V2” options
- Set “Allow legacy Manifest V2 extensions” to Enabled
- Relaunch Chrome
Now try reinstalling uBlock Origin from the Chrome Web Store. It might just work—for a little while longer.
Note: This is a temporary patch. Future Chrome updates may completely remove MV2 support.
Why Ad Blockers Matter: It’s Not Just About Annoying Ads
Most people think of ad blockers as tools to stop intrusive popups. But that’s just the surface. Ad blockers are vital for security, privacy, and even mental health.
Here’s why they matter:
- Security: Many malware campaigns are delivered through malicious ads
- Privacy: Ads often include trackers that follow your browsing across websites
- Performance: Blocking ads can dramatically speed up page load times
- Battery/Data Savings: Fewer ads = less bandwidth and CPU usage
In fact, many cybersecurity firms and federal agencies recommend using ad blockers as part of basic online hygiene.
Chrome’s Dominance: Why This Affects Everyone
Let’s look at the browser market share:
- Chrome: 68.3%
- Safari: ~19% (mostly Apple devices)
- Edge: Chromium-based
- Firefox: 2.3%
- Opera/Samsung: Chromium-based
That means most browsers either are Chrome or built on Chromium. If Google dictates the rules for extensions, most browsers follow.
Real Alternatives to Chrome: It’s Time to Switch
Let’s talk options. If Chrome no longer serves the user, users must find new homes. Here are your best bets:
1. Brave Browser
- Chromium-based but privacy-focused
- Built-in ad blocking
- Still supports MV2 (for now)
- Open source
2. Firefox
- Non-Chromium engine (Gecko)
- Maintains MV2 compatibility
- Full support for advanced ad blockers
- Backed by Mozilla, a nonprofit foundation
3. LibreWolf
- Fork of Firefox with telemetry removed
- Focus on speed, privacy, and zero bloat
- Comes pre-configured with DuckDuckGo, HTTPS, and strong security flags
Installation is as simple as downloading the binary or using your Linux distro’s package manager.
Bonus Tip: Stop Using Useless Browser Extensions
Here’s a human confession: many of us overload our browsers with unnecessary extensions. Emoji pickers? Weather forecast widgets? Most of them not only bloat your browser but can also spy on you or worse—infect your system.
Rule of Thumb:
- Only install what you trust and need
- Audit your extensions monthly
- Prefer open-source extensions with code audits
Search Without Being Watched: Self-Host Your Own Search Engine
Google Search is great—for Google. Not for your privacy. If you’re serious about going off the grid, consider using SearXNG, a self-hosted search engine that aggregates results from multiple providers.
You can:
- Aggregate results from Bing, DuckDuckGo, and others
- Block ads
- Avoid data collection entirely
Once configured, it’s fast, light, and completely private.

Final Thoughts
What Google has done with Manifest V3 is more than just a technical change. It’s a signal: they want to control the user experience, even if that means hurting privacy and user freedom. But you don’t have to go along with it.
There are options. There are tools. There is freedom. And it starts with one click: switching your browser.
Don’t wait until every extension you love is gone. Don’t wait until the web becomes one big commercial. Take back control today.
