maybe we should check this, because we just don't know when they want to release 4.0. I didn't see anything if they want tot release 4.0 or 3.16 first. Though chromium will break with 4.0, we should just check agains Major, because it is just cleaner
```
#if NSS_VMJAOR >= 3 && NSS_VMINOR >= 15
```
