If you are looking for a good alternative to web browsers like Brave or Tor Browser, then you should know LibreWolf. It is a derivative of Mozilla Firefox, but modified to protect privacy and anonymity for the user. Among other things, an improved security system has been included, a search engine such as DuckDUckGo, Startpage, Searx and Owant, among others, as well as an integrated ad blocker and all telemetry functions have been removed, making it one of the browsers that respect your privacy the most.
Also, of course it's from open source, free, cross-platform (available for various Linux, OpenBSD, MacOS, and Windows distros), and quite promising in many ways. You just have to see its list of features to realize it:
