Questions people ask

Three things. A list of more than 29,000 network rules stops requests to known ad and tracker domains before they leave Firefox. Cosmetic filters then hide the empty slots those ads would have filled, including AdSense, Google Publisher Tag, Outbrain and Taboola containers. On YouTube, a dedicated script removes ad placements from the player's own data so videos play straight through.

No. Block Skip does not click the Skip button or fast-forward through ads. It runs before YouTube's own scripts and strips the ad placement data out of the player responses, the same approach the major open-source blockers use. The player never sees an ad to play.

YouTube handling is always on. It does not look at your allowlists, so allowing youtube.com will not bring ads back there.

Yes. There is no paid tier, no account and no sign-up. Install it from Firefox Add-ons and it works.

Block Skip is built and published for Firefox, version 140 or newer, on Windows, Mac and Linux. It is not available on Firefox for Android.

Click the Block Skip icon while you are on the site. Under Allowlist, choose Add next to This site to allow the whole domain, or next to This page to allow only the exact address you are on. With auto-refresh on, the page reloads immediately. You can also type domains and page addresses by hand on the settings page.

Site entries match the exact hostname for cosmetic filtering and include subdomains for network rules. If a page still looks off after allowing it, reload once so the earlier cosmetic changes are cleared.

This add-on requests permission to update your default search engine to Google. When it installs, Firefox asks whether you want to use Google by Block Skip as your default. Searches then go to search.blockskip.com, which returns Google results. This is how the add-on is supported.

You can say no at install time, and you can change your default at any time under Settings, then Search, in Firefox. Blocking works the same either way.

It depends on the technical and interaction data setting Firefox shows for the add-on. When that is allowed, Block Skip sends setup, attribution and search-status reports to api.blockskip.com: install and device details such as the extension and browser versions, random install and session identifiers, and attribution codes when present. When it is not allowed, those reports are not sent and are not queued for later.

Search terms go to search.blockskip.com only when you search with Block Skip. Your browsing history and the pages you visit are not collected. The full details are in the privacy policy.

Open the popup and add the page (or the site) to your allowlist, then reload. That confirms whether blocking caused the problem. If it did, send us the address through the contact page so we can adjust the rules for everyone.

Yes. Flip the Dark mode switch at the bottom of the popup. It applies to the popup and the settings page and uses the same burgundy and peach palette on a warm charcoal background.

Open Add-ons and themes in Firefox, find Block Skip and choose Remove. The uninstall page has the full steps for Windows and Mac, plus what to check for your search engine afterwards.
