UltraBlock is a browser extension for Chrome, Edge and FireFox. It is an all-in-one adblock and privacy protection extension that blocks ads, invisible trackers and third-party cookies. It makes websites load super-fast and prevents third-parties from tracking you online.
When you visit a website, you don’t think about everything that is loaded into your browser. You read the text, look at the images and click on a hyperlink in the navigation to the next page. While you are browsing a website many things are loaded in the background. Websites use analytics software like Google Analytics or Matomo, load functionally from social media platforms or run ads. An average website loads five different external services.
Most of these external services are not relevant for you. They are unnecessary, slow down your browser and possibly track and profile you without you knowing it. External services can detect your exact location, device, browser, behavior and in many cases track you while you visit different websites. That’s why we created UltraBlock.
How it works
When you visit a webpage, for example venturebeat.com, your browser starts by downloading the HTML code of that page. It will start to translate the HTML code into a visual page that you can see in your browser, we call this process rendering.
A part of the rendering process is loading all the individual elements like stylesheets, images and scripts. If these elements are hosted on a different domain, then we know it is an external element, or as we call it, an external service. By using our ad and trackers database we know what these external services are used for and blocks the once that are unnecessary.
Ad and tracker database
UltraBlock manually identified 25.275 hostnames and created a publicly available database out of it. It contains popular third-party services including their name, description, logo and hostnames that are owned and operated by the same owner. UltraBlock uses this database to identify and block unnecessary ads and trackers making your browser faster and protecting your privacy.
At the top right of UltraBlock there is an on and off toggle. When you turn off UltraBlock you can exactly what third-party services are loaded in the background of a website. Additionally, you can see in what countries they store your data.
External services can detect your exact location, device and browser. Because in many cases they are installed on many websites that you visit they can easily track and profile you. They keep track of what kinds of websites you visit, how long you stay there and what parts of a page you read and interact with. Most of these services can automatically be blocked by UltraBlock.
UltraBlock has different privacy protection features that prevent unknown services from tracking you. UltraBlock automatically deletes third-party cookies, clears the cache ow your browser so images can’t be tracked and can even randomize your user-agent.
We always keep on improving our service. When you installed UltraBlock your browser wil automatically update the extension to the newest version. In this changelog you can see what changes we made to the extension over time. Feel free to contact us if you have any questions or feature request.
