Network-level blocking
More than 29,000 declarative rules block requests to known ad and tracker domains, including their subdomains, before they leave the browser. Blocked requests never download, so pages carry less weight and fewer scripts run.
Features
Everything Block Skip does
Blocking at three layers, exceptions that are yours to set, and a popup that stays out of the way.
Blocking
Stopped early, cleaned up after
Cosmetic filtering
What network rules cannot reach, page-level filters hide. Block Skip collapses the empty containers left behind so layouts stay tidy instead of showing blank rectangles.
- Google AdSense and Google Publisher Tag slots and iframes
- Outbrain and Taboola recommendation widgets
- Common publisher ad-unit containers and named DFP slots
YouTube without interruptions
A script that runs before YouTube's own code removes ad placements from the player's data on every path YouTube uses to deliver it. The player has nothing to play, so there is no ad to skip. It also defeats the common tricks sites use to get a clean, unpatched network layer back.
- Nothing clicks the Skip button or fast-forwards
- Works on watch pages, playlists and embedded players
- Always on, independent of your allowlists
Control
Exceptions on your terms
Site allowlist
Allow a whole domain from the popup with one click. Use it for sites you want to support, or for the rare site that needs its own scripts to work.
Page allowlist
Keep the exception narrow. Allow just the exact page you are on and leave the rest of the site blocked. Page entries ignore query strings and trailing slashes so any variant of the address matches.
Auto-refresh
Reload the page automatically after an allowlist change so the result is visible right away. Turn it off if you would rather reload by hand.
Settings page
Site and page lists live on their own page, separate from preferences. Add entries by typing a domain or a full address, with validation before they are saved, and remove any entry with one click.
Everyday details
Small things done properly
Dark mode
One switch in the popup. The popup and settings page move to a warm charcoal background with peach accents.
Current-page panel
The popup shows the domain and path you are on, so you always know exactly what an Add button will allow.
No account, no sign-in
Nothing to register for. Lists and preferences are stored in your browser's extension storage.
Google by Block Skip search
This add-on requests permission to update your default search engine to Google. Firefox asks before it changes anything, and you can switch back in Firefox settings at any time. This is how the add-on stays free.
Good to know. Allowlisting applies to network rules and cosmetic filtering, not to YouTube handling. After you allow a page, reload it once so cosmetic changes made earlier are cleared. Requires Firefox 140 or newer.
