SuperchargePerformance separates cookie banner handling from cosmetic cleanup. **Auto-Reject Cookie Banners** is its own toggle and ships on by default. **Smart Page Cleanup** is a separate, opt-in toggle for CSS-based ad hiding and popup blocking.

## Auto-Reject Cookie Banners

Cookie consent banners fire before you can interact with a page. SuperchargePerformance uses the AutoConsent library to detect them and dismiss them by selecting the reject/decline path — not accept. The banner disappears. No click required, and no configuration needed — the feature is on from the moment you install.

AutoConsent supports hundreds of consent management platforms. Banners that use non-standard implementations may not be detected. In those cases the banner remains and you can click manually as usual.

## Smart Page Cleanup

Smart Page Cleanup is **off by default** — CSS injection can occasionally leave empty layout gaps where an ad slot used to sit, so the toggle is opt-in. It adds two behaviors when enabled:

### Cosmetic Ad Hiding

Some ad slots survive network-level blocking. The ad network's domain gets blocked, but the container div stays on the page — an empty box where an ad would have loaded. Cosmetic rules target those containers with CSS and collapse them.

These are CSS injections, not DOM removals. The page structure stays intact; the empty containers are hidden. Page functionality is unaffected.

### Popup Blocking

Unsolicited popups come from `window.open()` calls triggered by page scripts rather than user actions. Smart Page Cleanup intercepts those calls and drops the popup before the browser opens a new window.

Popups that follow a direct user click — OAuth flows, download dialogs, payment processor windows — are allowed through. The distinction is whether the `window.open()` traces back to a genuine user gesture within a 2-second window.

## When to Adjust These

Auto-Reject Cookie Banners and Smart Page Cleanup are controlled independently. If a site's cookie preferences need to persist (say, a subscription site you've already logged into), add that domain to the whitelist instead of disabling the feature globally.
