Apart from Adblock Plus, uBlock Origin is one of the most popular tools designed to filter content on websites and block persistent ads, pop-up windows or harmful scripts that steal confidential user data. Using uBlock Origin not only increases the comfort of surfing the Internet, but also protects the privacy of the user. During daily use of Web resources, the tool filters and blocks advertisements and spy components registering user activity, as well as protects us from browsing locations containing e.g.

malware. During its operation, uBlock Origin is based not only on its own filter sets, but also on the filters of the aforementioned Adblock Plus. Additionally, the tool also uses databases with entries concerning user's privacy and domains containing malicious software.

The user can, of course, define their own filters, rules or exceptions from the settings level. A huge advantage of uBlock Origin, apart from its efficiency, is the minimal need for system resources. The tool is available in the form of extensions for Firefox, Google Chrome and other browsers based on the aforementioned.
