Earlier quoted context omitted.
Seems a bit overkill to recompile to get "no third party cookies by default" when you can just open the settings and disable it when you first install the browser. The setting is kept between updates (in Firefox at least) and if you are paranoid you can always check with Dev tools or a dumping proxy that 3rd party cookies are still disabled after an update
This undervalues convenience. The convenience of not having to worry about privacy-hostile default settings. Also, this will not work where the user is running applications from read-only media, or using something like "Guest mode" on a Chromebook where changes to settings are either not possible or ephemeral. This sort of argument in defense of so-called "tech" company "default settings" shenanigans has been called…
> Some popular browsers are supposedly "open source" yet it appears no browser user longing for saner times has ever tried reversed this change and recompiling the browser for their own use. No third party cookies by default.
And my response was simply it's way easier for the vast majority of people to change a setting once, than compiling the source (and remember to stay up to date with new releases)
> What I do know is that most users do not change default settings.
And they don't install alternative privacy respecting browsers either.
