[Feature Request] LibreWolf prefers-color-scheme support

### Prerequisites

- [X] I [searched for any existing report](https://github.com/darkreader/darkreader/issues?q=is%3Aissue) about this feature request to avoid opening a duplicate.

### Is this feature request related to a problem?

Yes

### Feature Request Description

LibreWolf by default uses `resistFingerPrinting` which means that no matter what the `prefers-color-scheme` is set to in settings, it doesn't save properly. I am requesting that at the least darkreader readed the setting in librewolf and uses it for "detect dark theme" because it seems to not work. Ideally, reading the setting and giving it to users so that native dark modes work when applicable.
