McAfee Web Boost vs SuperchargePerformance: Tested (2026)

Key takeaways

• McAfee Web Boost does one thing: block autoplay videos. It’s bundled with a paid security suite.
• SuperchargePerformance blocks autoplay at two levels: one preserving YouTube and Meet, one blocking everything.
• Tab suspension, ad blocking, and a RAM dashboard come alongside. Want autoplay blocking, you get the rest too.

McAfee Web Boost shows up in speed-related Chrome searches primarily because autoplay blocking is one of the faster wins in browser performance. SuperchargePerformance also blocks autoplay — but as one of 11 features in a broader performance tool. The comparison is less about which is better at autoplay blocking and more about whether you need just that, or a full browser performance setup.

Feature Comparison

Stop Autoplay: How SuperchargePerformance Handles It

SuperchargePerformance’s Stop Autoplay feature has two distinct levels:

Both levels are free. The two-level design addresses a common complaint with blunt autoplay blockers: they break legitimate media interactions like muted thumbnail previews on video platforms. L1 preserves those interactions while still blocking background ad videos.

What a Speed Boost Extension Typically Does Not Cover

Autoplay blocking improves perceived page speed by stopping video assets from loading. That’s a real improvement. But it leaves untouched: RAM consumed by 30 inactive background tabs, ads and trackers loading on every page, scripts running in tabs you’ve barely looked at, and the latency between pages.

A narrow speed boost extension addresses one symptom. SuperchargePerformance covers all of these with 11 toggleable features, all running locally without outbound data transmission.

Privacy

SuperchargePerformance makes zero outbound network requests. All features run locally — no browsing data, URLs, or page content goes anywhere. The extension doesn’t run in incognito tabs.

McAfee Web Boost is part of a large security suite ecosystem. Its specific data handling isn’t independently verifiable from the extension alone.

Who Should Choose What

McAfee Web Boost may be sufficient if you are already in the McAfee security ecosystem and only need autoplay blocking, with no interest in ad blocking or tab management.

SuperchargePerformance is the better choice if you want autoplay blocking alongside tab suspension, ad blocking, and memory management — without requiring a separate security suite subscription.

Bottom Line

McAfee Web Boost makes sense if you’re already in the McAfee ecosystem and autoplay is all you want to tackle. For anything beyond that — tab memory, ad blocking, script control — you’d need additional tools. SuperchargePerformance covers the full range in one install, standalone, with no security suite dependency required.
