A guide details setting up uBlock Origin in Hard Mode by blocking third-party requests, large media, remote fonts, and JavaScript, then selectively unbreaking sites.
Adopting this configuration significantly reduces tracking and bandwidth by defaulting to blocking all third-party connections and scripts. Engineers will need to spend time manually unblocking specific third-party domains to restore functionality on sites that break under these strict rules.

The setup enables uBlock Origin's advanced user mode to block all third-party requests, scripts, and frames by default.
Users must import custom blocklists like oisd and hagezi and configure rules to block media over 32K and remote fonts.
The guide relies on dynamic filtering and the uBlock logger to identify and selectively allow necessary third-party connections when sites break.
