How do I use livery editor?

I tried to use the livery editor in Chrome, Opera, Firefox and IE and I can't use it. I installed Unity Web Player and restart the browsers but it still doesn't work. Anyone can help me?

Looks like your browser doesn't recognize that you have the plugin installed. Have you gone into browser app settings to enable it?

I'm using W10 64 bits. I've already tried everything and it doesn't work. I'll just forget it and play the game, i think it won't affect my gameplay, will it?

And thank you both for trying to help me.

Confirmed, Safari works, I believe Version 5.1.7 for windows. Hope this helps. Literally downloaded that POS explorer for the sole purpose of editing the livery, and no it may not make the cars faster but it makes them better looking when fighting your way through the mid field waiting to be competitive hahaha
