Change the color of this separators in about:preferences in the translation section?
Hello!
How could I change the separator color in about:preferences in the translation section?
When I put my code in userContent in @ -moz-document url("about:preferences#general")
It doesn't work, I guess that it's because it opens up in a new window, but when I put it outside of it it works, the only problem with that is that I don't know if it will also affect webpages.
