v.1.4.1

Mozilla said v1.4.0 was too fire for Firefox, so we dialed back the flames. _{jk not really. LOL. our builds weren't byte-for-byte consistent due to use of timestamps so they never passed Mozilla's byte-for-byte checks. ^{ya they're going that deep ¯\_(ツ)_/¯}}

But we also took this opportunity to patch some fraud calcs, thanks to y'alls bug reports! ♥︎
