Deobfuscating/Decompiling extremely complicated JavaScript

I am working with some extremely complicated JavaScript. It is around 70,000 lines long and sections of the code look like this

U2xx.l11="0x78920d50";m2xx.r9G="11";b2xx.v3y="0x744ebc37";P2xx.K5h="0x4949db92";k4vv.k7Q=1099;k4vv.j6Q=255;C2xx.m6V=7035;f2xx.S7U="0x88f07878";v2xx.U0z="10991";h2xx.c0b="2665";U2xx.T11="0xd52da96f";I2xx.O2z="10410";v2xx.H2k="450";B2xx.L7n=0x88;E2xx.X4y="0xe8";j2xx.f4h="0xd36ebdd3";M2xx.o21="0x30fa5520";Z2xx.T4b="6325";F2xx.s4G="9036";G2xx.L2r=0xf46e5918;b2xx.X3y="0xe11ce5ed";h2xx.y0b="8843";Q2xx.H3Z=5152;b2xx.V7y="0xe89c636e";S2xx.v3b="6598";n2xx.E5y="0x00000000";K2xx.x90="0x7f456253";E2xx.J8y="0x88";i2xx.C70="0x30f3dcb2";Z2xx.X1b="6970";G2xx.z2r=0x171d121b;k2xx.e35=0x9c;Y2xx.s80="0x9d342e53";i2xx.j70="0x937c69d0";S2xx.a5b="3997";s2xx.l0t="5261";h2xx.C0b="3278";l2xx.a40="0x0f9357e7";

I know the Javascript is used to generate cookies to authenticate post requests sent to a web server just I am struggling to figure out how with the extremely obfuscated variable names and values.

Are there any tools that will help me reverse the hex values and present variables in a nice way? I have tried several tools like jsbeautify, jsnice and also Malzilla but to no effect.

I have posted some more code below if this helps provide more context
