Per-site control

Full control, per site

Whitelist domains where features shouldn't apply. Toggle individual features per site — keep ad blocking active while disabling script control on sites that need it.

  • Banking, internal tools, legacy apps — add once and forget
  • Wildcards cover entire services: *.example.com
  • One-click bypass from the popup on any page

Using SuperchargeNavigation too? All four extensions work together.

  • RAM savings 30–60% less total memory usage
  • Features included 14 all running locally
  • Telemetry Zero no tracking, no accounts

14 features. One extension.

Each one attacks a different source of browser bloat. Together, they compound.

Tabs and memory

  • Sleep idle tabs

    Free up 90–95% of each idle tab

    Idle tabs quietly free their memory, then reopen right where you left off — same scroll position, no lost state. Configurable timing puts you in control.

  • Lighter background tabs

    Reduces how often background scripts can run, freeing CPU for the tab you're actually using.

Blocking

  • Ads and trackers

    Blocked before they run

    Blocklists stop page ads and trackers before they run. Free, on by default.

  • Video ads

    YouTube and Twitch

    Pre-rolls, mid-rolls, Shorts sponsors, and Twitch ad breaks all suppressed at the player layer.

  • Cookie banners

    Auto-rejects cookie consent popups.

  • Page cleanup

    Hides sticky banners and ads that survive blocklists.

  • Third-party scripts

    Stop scripts you never asked for

    Manage third-party scripts per site. Reduce CPU and memory from trackers, analytics, and heavy frameworks running in the background.

  • Stop autoplay

    Prevents videos from playing on their own. Silence by default.

Page speed

  • Preload pages on hover

    Predicts your next click and starts loading in the background. Pages feel instant.

  • Load what you see first

    Loads on-screen content first, delays off-screen resources.

  • Faster connections

    Resolves domain names in advance so connections start faster.

  • Faster fonts

    Replaces slow custom fonts with fast system fonts. Pages render faster.

  • Block images

    Maximum speed for research and documentation sites. Strips all images.

Smart suspension

  • Sleep big tabs sooner

    Ranks tabs by memory use times idle time and suspends the heaviest idle ones first — not naive oldest-first.

  • Unsaved Form Protection

    Never suspends a tab with unsaved text sitting in a form. Your draft stays put.

  • Scroll-Position Restore

    Return to a suspended tab and it reopens exactly where you left off, scroll and all.

  • Conflict Detection

    Spots a rival suspender or blocker and warns you before two extensions fight over the same tab.

Recovery

  • Safe mode

    Detects when features break a page and automatically recovers. Zero config.

SuperchargePerformance

Frequently asked questions

Is SuperchargePerformance free?
Yes. Core features are completely free with no account required and zero telemetry. PRO unlocks advanced settings — manual suspension timing, full script blocking, background throttling, and more — for a one-time payment.
How much memory does it save?
Each suspended tab frees 90–95% of its RAM. Combined with ad blocking and script control, users typically see 30–60% less total memory usage. Open your task manager before and after to see the difference.
Does it work with other extensions?
Yes. SuperchargePerformance is designed to complement other extensions. The per-site whitelist lets you disable specific features on sites where they conflict, with one-click bypass per domain.
What data does it collect?
None. Zero telemetry, zero analytics, no account required. Your browsing history and tab data never leave your device.
What's the difference from Chrome's built-in Memory Saver?
Chrome Memory Saver only suspends tabs when memory is critically low. SuperchargePerformance adds proactive intelligent suspension with configurable timing, full ad and tracker blocking, per-site script throttling, domain whitelisting, adaptive memory-aware suspension, and 8 more optimization features — a complete performance toolkit versus a single fallback feature.
Does SuperchargePerformance work on Microsoft Edge?
Yes. SuperchargePerformance is available natively on the Microsoft Edge Add-ons store (approved May 2026). Edge is Chromium-based, so you get the exact same extension with all features: tab suspension, ad and tracker blocking, YouTube and Twitch video ad blocking, script control, and more. Install directly from the Edge Add-ons store in one click — no "allow extensions from other stores" toggle required.
