I've been using LibreWolf (FF based) for years now and I love this thing. There are many issues coming with anti-tracking, sometimes a pain in the ... but, whenever I ask myself "what if I had to switch to Brave or other" I always end up with the same firm "Nah, I'm good".

If LibreWolf would disappear, it would still be FF for me, with carefully selected and regularly reviewed privacy settings.
