Tab Suspender, Memory Saver & Ad Blocker — Web Boost by SuperchargeBrowser

Tracking since Apr 5, 2026.

Changelog

• May 2, 2026
  description

  Speed up Chrome and save memory. SuperchargePerformance suspends inactive tabs to free up to 95% of their RAM, blocks ads and trackers to cut active tab memory by up to 50%, and optimizes page loading — all built on Chrome's latest APIs.
  
  Chrome's built-in Memory Saver only suspends tabs. SuperchargePerformance goes further: it reduces memory on your active tabs too, by blocking the ad scripts, trackers, and third-party code that consume the most resources. A modern, safe alternative to The Great Suspender, FasterWeb, and McAfee Web Boost.
  
  
  🔒 ABOUT PERMISSIONS
  Chrome requires "read and change data" permissions for tab suspension and network-level blocking. SuperchargePerformance uses these permissions only to optimize performance — we never track, collect, or transmit your browsing data. Zero telemetry. Every optimization runs locally on your device.
  
  
  HOW IT WORKS
  
  SuperchargePerformance optimizes Chrome at every level — from idle tabs consuming RAM in the background, to the ads and scripts slowing down the page you're reading right now.
  
  Suspend Inactive Tabs
  Automatically frees RAM by suspending tabs you're not using. A single tab uses 50-300 MB of memory; a suspended tab drops to under 10 MB. Audio-aware — tabs playing music or video are never touched. Adjustable timing: 15-minute, 5-minute, or custom intervals.
  
  Block Ads, Trackers & Annoyances
  Intercepts ads, trackers, analytics, and malicious sites at the network level using Chrome's built-in content filter — the fastest, most secure blocking method available. Prevents memory-heavy ad scripts from ever loading. Three levels from common ads to maximum protection including phishing sites. 186,000+ blocking rules across 22 sources, kept current.
  
  Block Video Ads on YouTube & Twitch
  Removes ads before they reach the video player — no mid-video interruptions, no seeking back to where you were. On YouTube, ad metadata is stripped before the player processes it, so playback starts cleanly. On Twitch, pre-roll and mid-roll ads are blocked while preserving full stream quality. Both can be toggled on or off independently from the settings panel.
  
  Reject Cookie Banners Automatically
  Detects and declines cookie consent popups from 100+ consent providers. No more clicking "Reject All" on every site. Removes overlays without breaking page scrolling or layout.
  
  Stop Video Autoplay
  Prevents videos from playing automatically in the background, saving CPU and bandwidth. Two modes: Allow Common (permits YouTube and conferencing tools) or Block All (stops everything including muted hover previews).
  
  Control Third-Party Scripts
  Manages external scripts that add page weight and slow loading. Three levels from blocking social widgets and comment sections to blocking all third-party scripts with critical exceptions for login and payments.
  
  Preload Pages on Hover
  Predicts your next click and starts loading the page before you click it. Uses Chrome's native preloading for instant page transitions. Same-site or all-pages modes.
  
  Safe Mode
  If an optimization breaks a page, Safe Mode detects the issue and shows a one-click recovery toast. Disables optimizations for that tab so you can keep browsing — no need to disable the extension or dig through settings.
  
  Prioritize Visible Content
  Loads on-screen content first and delays off-screen images, iframes, and scripts. Pages become interactive faster because resources you can actually see are loaded first.
  
  Optimize Web Fonts
  Blocks heavy custom web fonts and substitutes fast system fonts. Reduces download size and speeds up text rendering. Three levels from removing non-essential font variants to forcing a single optimized system font.
  
  Predictive DNS Prefetching
  Resolves domain names before you need them. Pre-connects to your most-visited sites so pages start loading instantly.
  
  Smart Page Cleanup (optional, off by default)
  Removes leftover ad containers, sticky banners, and floating overlays that remain after blocking. Also blocks unwanted popup windows while allowing login flows and payment prompts through. Enable it in settings for a cleaner browsing experience across most sites.
  
  
  WHITELIST & CHROME DISCARD PROTECTION
  
  Need Figma, ChatGPT, or Google Docs to stay alive in the background? Whitelisted sites bypass all optimizations AND are protected from Chrome's own tab discarding — your important tabs won't lose state or reload when you switch back. One click to whitelist.
  
  
  WHO IT'S FOR
  
  • Chromebook users on 4GB/8GB devices — stop the lag and freezes that come from too many open tabs.
  • Laptop users who need longer battery life — less background activity means less heat and more runtime unplugged.
  • Anyone with 20+ tabs open — Chrome wasn't built for that. This extension is.
  
  
  PERFORMANCE DASHBOARD
  
  Track your impact: total RAM saved, ads blocked, scripts controlled, time saved, and pages optimized — all calculated locally from your actual browsing activity.
  
  
  PRIVACY & SECURITY
  
  SuperchargePerformance never tracks, collects, or transmits your browsing data:
  • Every optimization runs locally on your device
  • No browsing history, search queries, or page content is collected
  • No cloud servers, no accounts, no sign-up required
  • Built on Chrome's latest security model
  
  Available in 28 languages. Works on Chrome, Chromium, Brave, and Edge.
  
  Free to use. PRO available for power users who want maximum control.
