Catblocker — Replace Ads

CatBlocker transforms your browsing experience by replacing intrusive online ads with delightful cat pictures. Instead of distracting banners, sponsored blocks, or awkward empty spaces, you are greeted by playful kittens and calming feline images that bring a smile while you browse. The extension works quietly in the background, detecting ads in real time and swapping them with high-quality cat photos without slowing down your browser.

CatBlocker gives you control over how it behaves: you can adjust the intensity of ad detection from gentle to aggressive, whitelist websites you want to support, and even upload your own custom cat images to make the experience more personal. A clean popup dashboard shows you how many ads have already been replaced, both on the current page and across all your sessions, so you can see the impact instantly. For those who love flexibility, the options page allows easy management of your preferences, from maintaining a whitelist to importing and exporting your settings.

With a simple toggle, context menu integration, and a polished interface designed for both light and dark modes, CatBlocker is more than just an ad blocker. It is a way to make the web feel lighter, friendlier, and far more fun. If ads frustrate you but you still want your pages filled with something positive, CatBlocker ensures that every interruption turns into a moment of joy.
