You can switch to dark mode and affect the whole UI, which you may not like. If you do not want to affect the rest of your browsing experience, here is a way to do this (I have done it as well) but it requires your concentration for about 10 minutes as you need to follow instructions carefully. Make sure to set up userchrome.css correctly as this is not a user-friendly nor straightforward proccess. Reply in case of any issues.
