Light-weight, fast browser extension for Firefox and Chromium (Chrome, Edge, Brave Opera etc), that blocks tracking, ads and known malware. uBlock is easy-to-use out-of-the-box, but also has a highly customisable advanced mode, with a point-and-click firewall which can be configured on a per-site basis.
