The opt in by default in Brave vs Firefox's opt-out by default does speak value. While a feature can be good/suggested to be enabled, a user won't know to look for it unless advertised or in settings. Most of the features in Firefox seem to be behind about:config changes. I imagine most users just install software and go on with their life instead of configuring. Can be a double edged sword though. No sites that are memorable off hand, but I have had site that Brave with Shields w/defaults would not load vs stock firefox + stock Ublock would. Note sure if this is due to the "opt in" by default breaking a site. Edit: Brave is opt out, Firefox is opt-in. I had them backwards.
