Maybe it’s age? I used Firefox since firebird, and Phoenix, and Netscape, but saying “try Firefox” might feel like talking about an archaeological relic to a 28 year old who has never even seen Firefox running.
How tone deaf can people be?
I talked to brave supporters and they all say "Firefox is a pita to modify" but we have had waterfox and other derivatives, floorp and others for decades.
In the end, Brendan is the one who does not like Firefox for personal reasons and that's why brave isn't based on Firefox. Personal reasons but brave fanboys don't see it
