Have you ever been frustrated by the amount of irrelevant results that come up when you perform a Google search? Or have you ever wanted to protect your children from certain unwanted websites? The solution could be found in an open-source extension called uBlacklist. This powerful yet easy-to-use tool allows you to customize your search results for an optimized browsing experience.
uBlacklist is a browser extension that allows you to block specific sites from Google search results. Developed for Chrome, Firefox, and Safari, this extension is particularly useful for eliminating irrelevant, unwanted, or inappropriate results from your searches. If you want, for example, to protect your children from certain content or to obtain more targeted search results, this extension is the tool for you.
How uBlacklist works
As its name suggests, uBlacklist allows you to create a "blacklist" of websites or domains that you do not want to appear in your search results. Very useful for google search, it is interesting to note that the extension's filters also work with other search engines such as Bing, Brave, DuckDuckGo, Ecosia, Qwant, Searx, Startpage.com, Yahoo! Japan, and Yandex.
How to use uBlacklist to block sites
- Install the extension: Head to the Chrome Web Store, Firefox Add-ons Store, or Safari Extensions Store to install uBlacklist on your favorite browser (or the extension's GitHub page which links to each store).
- Adding sites to your blacklist: When you perform a google search and you find a site you want to block, click on the “Block this site” option added by the extension to the search results. You can also manually add sites to your blacklist by going to the extension’s settings.

- Use regular expressions: For advanced users, it is even possible to use regular expressions in the extension configuration. The uBlacklist official page contains many examples to help you master this feature.
For example with the expression:
/^https:\/\/www\.exemple\./
You will block the domain name “example” and all its extensions (.com, .fr…).
- Sync your filter lists: If you use multiple browsers or devices, it is possible to sync your filter lists with Google Drive or Dropbox for easy access to your custom filters.
- Subscribe to public filters: To block commonly unwanted sites, subscribe to public filters created by other extension users that you can find here.

In a digital world where information is omnipresent, it is essential to filter content to obtain relevant results. Search engines, despite all their sophistication, cannot always know exactly what we are looking for.
The uBlacklist extension then appears as a real breath of fresh air. It gives you the control you have always dreamed of over your search results. With it, not only will you avoid distractions and gain in productivity, but it will also redefine your web search experience. It is the opportunity to create a search space adapted to your preferences, without the usual hassle of manual sorting. By allowing advanced customization, uBlacklist becomes an essential tool for anyone who takes their online research seriously.
