# SuperchargePerformance 1.4.6 — Ad Blocking That Repairs Itself

> Your ad blocking now repairs itself. When Chrome fails to load the blocking rules — often because another ad blocker uses up the shared rule budget — the popup detects it, repairs it automatically, and says so. Third-party script blocking now blocks analytics and tracking scripts by default instead of breaking YouTube embeds, Disqus comments, and Facebook Login. Spotify, YouTube's video servers, Intercom, Stripe's payment checks, SmartScreen, eBay, and Google sign-in are no longer blocked by mistake, and a routine security pass made the popup's controls and extension messaging stricter. No new permissions.

## Highlights

- When Chrome fails to load the blocking rules — often because another ad blocker uses up Chrome's shared rule budget — the popup now detects it, repairs it automatically, and says so
- Third-party script blocking now blocks analytics and tracking scripts out of the box, instead of breaking YouTube embeds, Disqus comments, and Facebook Login
- Spotify, YouTube's video servers, Stripe's payment checks, Microsoft SmartScreen, eBay, and Google sign-in are no longer blocked by mistake
- A pre-submission security review tightened how the popup and our extensions talk to each other, and a round of layout fixes tidies the popup

## Your Ad Blocking Now Repairs Itself

Chrome sometimes fails to load an extension's blocking rules — after an update, or when another ad blocker uses up the rule budget Chrome shares between extensions. That failure used to be silent. The extension now checks, repairs automatically when you open the popup, and confirms: "Ad blocking restored." If the automatic reload doesn't take, a banner offers a one-press retry, and when another ad blocker's rule budget is the cause, it says so.

## Trackers Blocked, Embeds Left Alone

Third-party script blocking has two levels, and they were swapped. The default blocked nothing that tracks you but broke YouTube and Vimeo players, Disqus comments, and Facebook Login. It now blocks analytics and tracking scripts — and pages look no different. Embed and social-widget blocking is still there; it's just no longer the default. Anyone on the embed-blocking level is moved to the new default once; set it back and it stays.

## Sites That Were Blocked by Mistake

Our blocklists come from public ad and tracker lists, and one of them included domains real sites need: Spotify's streaming servers, one of YouTube's video servers, Intercom's support chat, Stripe's payment checks, Microsoft SmartScreen, and part of eBay's API — all excluded now. Google's "Sign in with Google" prompt on other sites was also blocked in some countries and not others; it's now blocked nowhere. Exclusions cost no blocking: these levels fill to a fixed rule count, so each freed slot goes to the next domain in line.

YouTube's video server and Stripe already had exceptions on the books that weren't doing anything — a whole-domain exception only ever covered its exact address. Fixing that also woke a set of dormant bank exceptions that were broader than they should have been; those are now pinned to exact addresses.

## The Font Setting Says What It Does

Font blocking now spells out what it really does: it blocks Google Fonts entirely, icon fonts included, which is why icons can occasionally show as blank squares. The behavior hasn't changed — the setting just explains itself properly now, on all three levels.

## Strengthened in Review

Every release goes through a security review before submission, and this one came out stricter for it: the channel Performance uses to talk to Navigation is now locked to our own extensions, and the card offering to pause blocking on a broken-looking site responds only to a real click from you. Proactive hardening — nothing was ever observed misusing either.

## Housekeeping

The cookie banner auto-reject engine is refreshed, now covering hundreds of consent services. A warning that guessed at conflicts with other ad blockers is gone — it could only ever fire in error. The popup also picks up a batch of layout fixes: long site names truncate cleanly, one bad whitelist entry no longer blanks the list, and the header never claims a blocking level it isn't delivering. All told, the three blocking levels carry just over 195,000 rules, and no new permissions were added in this release.
