Adaptive Suspension, Ambient Feedback & Popup Redesign

Performance v1.4.0

SuperchargePerformance now suspends smarter. Instead of picking the oldest idle tab, the engine scores every tab by memory used × idle time — so a 400 MB tab that's been idle ten minutes gets suspended before a 30 MB one that's been idle twelve. Tabs with unsaved form data are skipped automatically. A new memory fast-path mode can suspend heavy tabs before the idle timer even fires. The popup is redesigned: one panel, a live status line that counts down to the next check and confirms each suspension, and a Silent toggle that mutes ambient signals without touching the toolbar icon. AutoConsent jumps to 14.84.0 — 760 rules across 1,447 sites. Blocklists refreshed across all 22 sources.

  • Adaptive suspension ranks tabs by memory × idle time — not oldest-first
  • Tabs with unsaved form input are protected from suspension automatically
  • Memory fast-path mode suspends heavy tabs early, before the idle timer
  • Redesigned popup consolidates controls with a live status line under the suspend button
  • Ambient feedback — toolbar state icons, RAM counter, edge flash, logo toast
  • Silent toggle mutes all ambient signals without affecting the toolbar icon
  • Conflict detection surfaces a banner if another ad blocker interferes
  • Microsoft Edge support — same MV3 codebase runs on Edge; edge:// internal pages handled alongside chrome://
  • AutoConsent upgraded to 14.84.0 — 760 rules covering 1,447 sites

Adaptive Suspension

The suspension engine no longer picks the oldest idle tab. It now scores every eligible tab by memory used × idle time — so a memory-hungry tab that’s been idle for a while gets suspended before a lightweight one that’s been idle longer. The result: the browser frees RAM faster, and low-memory tabs you actually use stay alive longer.

Two things happen in a single lightweight probe before any tab is suspended: the engine reads its JavaScript heap memory and checks for unsaved form data. Tabs with unsaved input are automatically protected and skipped.

The old three-tab floor is gone. The engine suspends whenever any tab qualifies and skips a cycle only when nothing is eligible. After the browser wakes from sleep, it reschedules its check so suspension doesn’t go stale on a resumed machine.

Memory Fast-Path

A new opt-in mode suspends memory-heavy tabs early — before they hit the normal idle timer. Off by default. When enabled, threshold sliders let you set the memory cutoff (default 200 MB) and the minimum idle time before the fast-path can fire (default 5 minutes).

Available on Medium and higher suspension levels. Threshold customization is a PRO feature.

Redesigned Popup

The suspension controls are consolidated into one panel. The most visible change is the status line directly beneath the Suspend all now button.

Before a check runs, it counts down to the next automatic suspension. After a check runs, it shows the result for a few seconds — “Just suspended 3 tabs”, “All idle tabs already suspended”, “Nothing to suspend”. Click the button when nothing’s eligible and it says so explicitly instead of reporting “Suspended 0”.

A brief green flash confirms a successful manual suspension. The per-tab Lock button is removed — whitelisting a site already exempts it from suspension and survives restarts, making the lock redundant. Tooltips across the popup share one consistent style.

Ambient Feedback

Four quieter ways to see the extension working without opening the popup:

  • Toolbar icon — distinct states for active, paused, and playing
  • RAM counter icon — tracks gigabytes of memory recovered
  • Edge flash — a brief pulse at the page edge when an ad or tracker is blocked
  • Logo toast — a small notification top-right on significant events

The pulses and toasts can be muted with the Silent toggle in the popup header. Silent mode suppresses the edge flash and the toasts — but never the toolbar icon, its RAM counter, or the safe-mode recovery notices.

In-Popup Help

A Help overlay opens inside the popup — no new tab, no context switch. When something looks off, it points you to the right toggle rather than suggesting a reinstall.

Conflict Detection

If another ad blocker appears to be interfering with SuperchargePerformance, a passive signal surfaces a banner so you can resolve the overlap. It waits 48 hours after install before it can appear and clears itself once the conflict heals.

Each feature’s ? in the popup now opens that feature’s own page on superchargebrowser.com instead of a generic doc. Faster to find what you’re looking for.

The cookie banner auto-rejection engine (DuckDuckGo AutoConsent) is upgraded from 14.67.0 to 14.84.0 — 760 rules covering 1,447 sites. More consent management platforms handled, faster dismissal on the ones already covered.

Refreshed Blocklists

All 22 sources refreshed. 186,616 rules across three tiers: 100K ad and tracker domains (Free), ~65K privacy and telemetry (Medium), ~22K malware, phishing, and fraud (Pro). Domains ranked by real-world traffic impact so the highest-reach networks are blocked first.

Microsoft Edge Support

SuperchargePerformance now runs on Microsoft Edge — same install, no separate version. Edge uses its own internal URL scheme (edge:// instead of chrome://), so every place the extension skips a browser page — tab suspension, cosmetic ad-hiding, auto-discard, and the popup’s per-site check — now recognizes edge:// pages alongside chrome://. Suspension and blocking run natively on Edge without touching its internal pages.

Under the Hood

Cosmetic ad-hiding stops scanning sooner on static pages, reducing CPU use on pages that settle quickly. No new permissions were added — every new signal in this release reuses existing APIs.
