I think we need all support we can get to fight Google on this, so I welcome Brave here actually.

I use brave and this is built in and still gives me the protections offered by Brave.
What protections does this offer?
Additionally I see mention of electron in the code!!!
Ferdium is based on electron. But it actually uses it to render websites. It’s slick and handy. When talking about profiles, I mean in Firefox, which will grand you all the protections you need. If you need to add addons or change settings, with the user.js config, you will need to type about:setthings or about:addons rathet then cluck on a few buttons, but if all you use it for is just a few sites working in a single window, it’s fine.
