LibreWolf

LibreWolf is for people who love Firefox but don't trust the "default" settings. It is a custom build of Firefox that strips out all telemetry, data collection, and non-essential features like Pocket or sponsored shortcuts. It pre-installs uBlock Origin, widely considered the best ad blocker available.

It applies a set of "hardened" settings out of the box—disabling WebGL to prevent fingerprinting, enforcing strict cookie policies, and clearing history on exit. This saves you the hours it would normally take to configure Firefox to this level of privacy.

Because it is so strict, it can sometimes break websites (like video streaming or complex web apps). It also doesn't include Firefox Sync by default (for privacy reasons). It’s a tool for users who are willing to sacrifice a little convenience for maximum privacy integrity.
