Hi,
Thanks for your rating. It's great to hear that you like the add-on.
I see, however, that you are having a problem with some sites and I'd like to apologize for that. Unfortunately, some sites may always cause issues.

I'm about to release a new version of the add-on, which improves compatibility for some sites. Maybe it helps you too.
If you have further issues or questions or the issue stays unresolved, feel free to ask or suggest a feature by opening an issue on https://github.com/rugk/website-dark-mode-switcher/. Thanks.

Again I'm sorry for the inconvenience. If you want, you could try out a development version on GitHub and adjust your rating.

Best regards,
rugk
