Changelog

Theme-Aware Icons

The toolbar icon now adapts to your system theme. Light mode shows the classic blue bird; dark mode switches to an amber variant. The popup logo follows the same theme logic for a consistent experience.

RAM Counter Badge

The toolbar icon is replaced by a canvas-rendered badge showing how much RAM you’ve saved — displayed as a stacked number and unit (e.g. “4.2 GB”). The badge uses the extension’s blue brand color in light mode and a black background with white text in dark mode.

Cross-Promotion Banner

Users who’ve had the extension installed for 7+ days will see a dismissible banner promoting SuperchargeNavigation — our vertical tabs and workspaces extension. The banner uses the same visual language as the rating milestone banners and can be permanently dismissed with one click.

Timed Pause & Resume

The global on/off toggle now supports timed pause — disable all optimizations temporarily and have them automatically re-enable after the chosen duration.

Locale & Listing Updates

• Added Arabic (ar) locale
• Optimized German (de) and Turkish (tr) CWS listing titles and descriptions
• Updated CWS promotional tiles and marquee with new brand-consistent design

Refreshed Blocklists

All upstream blocklist sources have been refreshed. The compilation produces 186,567 rules across three tiers: 100K ad/tracker (Free), 65K privacy/telemetry (Medium), and 22K security/threats (PRO).

SuperchargeNavigation is Live

SuperchargeNavigation brings vertical tabs, workspaces, and instant search to Chrome — built entirely on Chrome’s native Side Panel API. No new windows, no separate processes, no performance overhead.

Vertical Tabs

A full vertical tab list in Chrome’s side panel. See all your tabs at a glance with favicons, titles, and audio indicators. Drag to reorder. Right-click for quick actions.

Workspaces

Group tabs into named, color-coded workspaces. Switch between work, personal, and project contexts instantly. Workspaces persist across browser restarts.

Instant Search

Fuzzy search across all open tabs — find any tab in milliseconds. Keyboard-driven: press the shortcut, type, hit enter. No mouse needed.

Time Travel

Browse and restore recently closed tabs with full session context. Never lose a tab again.

Privacy First

Zero telemetry, zero analytics, zero network calls. All data is stored locally in Chrome’s storage API. Nothing leaves your browser.

Rebrand to SuperchargePerformance

The extension has been renamed from “SuperchargeBrowser” to “SuperchargePerformance” to clearly distinguish it from SuperchargeNavigation — our new vertical tabs and workspaces extension. All in-extension UI, CWS listings, and localized descriptions have been updated across all 27 supported languages.

Refreshed Blocklist Sources

The entire blocklist stack has been refreshed with the latest upstream sources. The new compilation produces 186K+ declarativeNetRequest rules across three tiers (Free, Medium, and PRO), with stale chunks automatically cleaned before recompilation.

Stability & Compatibility Fixes

• Frozen tab handling: Tabs in Chrome’s frozen state (Chrome 132+) are now correctly skipped during suspension checks
• Safe Mode reliability: Fixed DNR session rule cleanup, pushState navigation guard, and toast theme support
• Prioritizer performance: Deferred IntersectionObserver initialization until after first layout pass to avoid blank-page race conditions
• Fresh install blocking: Resolved an issue where content blocking rules weren’t applied on first install
• Dashboard accuracy: Improved RAM calculation methodology and metrics flush timing
• Site toggle: Fixed popup whitelist toggle not reflecting the correct state on reopen
• CWS listing optimization: Updated titles and descriptions across 27 locales with improved keyword targeting

Architecture Rebuild

Version 1.2.0 is the most significant upgrade yet — a complete migration from Vite + CRXJS to the WXT framework with TypeScript strict mode, bringing proper hot module replacement for popup development, structured manifest generation, and a modern build pipeline.

Cookie Banner Autopilot

Stop clicking “Reject All.” SuperchargePerformance now automatically detects 100+ Consent Management Platforms and programmatically declines tracking on your behalf. Unlike older blockers that just hide the banner (breaking the page), the engine legally opts you out and cleanly unlocks the screen. Powered by DuckDuckGo Autoconsent.

Zero-Latency Navigation (Now Free)

Previously exclusive to PRO, “Preload on Hover” is now available to everyone. The extension predicts your next click and pre-fetches the destination in the background, making navigation feel instantaneous.

Safe Mode Recovery

Aggressive blocking sometimes breaks complex web apps. The new smart-detection feature catches rendering errors and provides a one-click “Safe Mode” toast to instantly unbreak the page for your current session — without needing to dig into settings.

Advanced Video Autoplay Control

Stop hidden videos from eating your CPU and bandwidth. Choose “Allow Common” (permits YouTube, Google Meet, but blocks generic sites) or “Block All” for absolute silence and maximum battery savings.

Milestone Achievements

The dashboard now actively tracks your lifetime optimization metrics. Hit the 5 GB, 25 GB, and 100 GB “RAM Saved” milestones to unlock new dashboard tiers.

Technical Enhancements

• Filter list overhaul: Migrated to a modern blocklist stack, purging 100,000+ obsolete legacy rules to reduce baseline memory while adding active malware and phishing protection
• SPA compatibility: Resolved “blank window” conflicts where aggressive ad rules blocked core JavaScript bundles on heavy Single Page Applications
• Whitelist overrides: The whitelist toggle now completely bypasses Chrome’s native discarding API, ensuring mission-critical tabs are never suspended

Performance Dashboard

A new interactive dashboard provides real-time insights into your browsing optimizations. Track RAM saved through tab suspension, ads blocked by content filters, time saved, pages enhanced, and scripts managed — all presented with smooth animations.

Enhanced Controls

• Global toggle: Enable or disable all features with one click for seamless performance management
• Per-site whitelist: Instantly customize settings for individual websites, ensuring optimal performance where it matters most

27 Languages

SuperchargePerformance now supports 27 languages including Spanish, French, German, Japanese, Chinese, and more — removing barriers to optimization for users worldwide.

Technical Enhancements (v1.1.0)

• Reduced package size: Eliminated unnecessary metadata from Chrome Web Store uploads for faster downloads
• Improved storage handling: Strengthened Chrome API integration with robust error handling
• Better onboarding: Improved tooltips and contextual help throughout the interface
