I really, really want to love this extension but there are two main problems that keep me from having it installed.

1) It slows down your browser A LOT. Even on my high end gaming PC, websites load much slower and some will even hang until you disable the extension and refresh the page.

2) Sometimes the style changes don't "kick in" right away so you'll get a flash of white when you first visit a page. While this isn't a huge deal during the day, when it's night time and you've been browsing in all black for a while it feels like staring at the sun.

I continue to re-download Dark Reader every few months to give it another shot, but these problems still persist. It's a great idea, but the execution needs some work.
