Firefox 48.0.2 / Firefox 45.9.x ESR on Windows XP RTM (and older OSes?)

[Uncle Captain]

I finally managed to get Firefox 48.0.2 to work on Windows XP RTM!

Notes

kernelxp.dll stays in the "firefox" directories after patching, or else it will NOT work.

The unofficial guide "How to get Firefox 48.0.2 / 45.9.x ESR to work on Windows XP RTM!" is now available. This guide is made by me.
