Ultima Version Chrome Xp

I downloaded a few mods and they show up in the mod menu, but when I check them on and restart the game, they turn off....
I put them in the Users\username\zomboid\mods folder and they all have mod.info files, which include the important stuff, and the name which is what it needs to work. So I know the mods themselves aren't broken, just not turning on for some reason.
Thanks,
Sok.
