This ad used too many resources for your device, so Chrome removed it.

“This ad used too many resources for your device and  Chrome removed it” means Google Chrome is working exactly as intended to protect your computer or phone.

You do not need to “fix” your device. The error appeared because the website you are visiting tried to load a poorly coded or malicious advertisement, and Chrome blocked it to prevent it from draining your battery or freezing your browser.

Here is the breakdown of why this happens and what you can do about it.

1. What triggered this?

Chrome has a built-in feature called “Heavy Ad Intervention.” It automatically kills any ad frame that exceeds specific technical limits. The ad you were about to see violated one of these three rules:

• It was too heavy on data: It tried to download more than 4 MB of data over the network.

• It was hogging the CPU: It tried to use the main processing thread for more than 15 seconds in a short 30-second window (or 60 seconds total).

• It was mining crypto: Sometimes, these “heavy ads” are actually scripts trying to mine cryptocurrency in the background using your hardware.

2. What should you do?

• Option A: Do Nothing (Recommended) You can ignore it. Chrome successfully killed the process, so it is no longer using your resources. The grey box is just a “tombstone” telling you what happened.

• Option B: Refresh the Page Often, ad networks rotate ads. If you press F5 (or pull to refresh on mobile), the heavy ad will likely be replaced by a lighter, compliant one, and the error will disappear.

• Option C: Install an Ad Blocker If you find the grey error boxes ugly or annoying, the best solution is to stop the ads from loading in the first place.

  • Recommendation: Install uBlock Origin (free and open-source). It will block the ad frame entirely so you won’t see the ad or the error message.

3. Note for Mobile Users

If you see this frequently on Android, it usually means the site you are visiting is poorly optimized. Using a browser with built-in ad blocking (like Brave) or using “Lite Mode” in Chrome can help save your data plan.

Summary:

Your device is fine. The website just served a “bad” ad, and Chrome took it out to keep your browsing smooth.
