The Start of Vulpine

SakuraBit is beginning the conception phase of Vulpine — our take on what Firefox could be if privacy came first, by default.

We believe Firefox is one of the best browsers out there. But to truly make it privacy-respecting, you need to dig through settings and install the right extensions to get a truly privacy-respecting tool. That gap is exactly what Vulpine is designed to close.

Our goal is to ship oure view of Firefox out of the box: the right privacy settings enabled, trusted extensions like uBlock Origin preinstalled, and a few additional tweaks to go the extra mile — all without asking anything of the user.

Vulpine will be fully open source and free for everyone.
