Be able to hide top bar completely

I have started to use other browsers frequently simply because of the different ways of they have setup the url bar, and the whole top part of the browser.

I started using safari on iOS simply because the URL bar was at the bottom, making it ergonomically much easier to navigate and use the URL bar.

Now that i have a large screen, and using a Macbook Pro, I've started using Arc because they hide the whole navigation tab, giving more space when you have multiple windows besides each other. The reason why this is great is that on OSX, you can only have full screen two windows, and i have so much space with the full screen that i need 3 separate windows besides each other. And it makes window managers easier to use then to drag and drop them over each other.

So my thought was that Firefox could have browser profiles that is able to fill different browser profiles. This can be done by giving more customization to the toolbar customization tool, or just have more "hiding" options, but other complementary options need to happen to make that work as well as Arc does.
