LibreWolf (I think this is linux-only)
Enjoy youre web browsing experience
One thing I do like to do is running Wireshark or tcpdump after configuring the browser to check and make sure its not making unsolicited connections. What kinds of web browsers do that ? Gee I wonder…(>.>)
Oh and if you can’t just ditch FF for some reason then you may consider using an older version: v58 or v62 or something like that as older versions generally spy on you less (yes they get worse by the year)
Also if the article says what I think it does; everyone’s own opinions are probably the best ones there is no need to let the world tell you who you are or who you ought to be in life.
