petui / Tiberium Alliances Wavy

Hi petui,

I use Firefox 64 bit version, and have the tamper monkey for Firefox on it.
I use your Wavy script.
--Tiberium Alliances Wavy--
Recently an update came out for Firefox (version 57.0.) Now the Wavy-script is not working anymore.

On Chrome synonymous with Tampermonkey the script goes perfectly.

Could you please adjust the wavy script for firefox to make it work again?

Thank you in advance !!!

Greetings, Pau

P.S .: Sorry for my bad english, I do not speak / write it perfectly
