You don't need to build one from scratch, but make a custom build of an
existing open source browser (e.g., from firefox, konqueror or
chromium), say for removing some unnecessary 'features' or tailor it for
special environment (e.g., remove/disable tcp to be sure it's on tls
always). This kind of 'forking' is legit, anyone can do it without
breaking exiting license and such variants already exist (ed).
