Does a decent job at making pages darker. Not perfect, but it's free. However, I've also experienced broken functionality on more than one website, and that's a big no, no.I won't give it a bad rating because it is free and open source, and works well enough most of the time. But it does need some work.

Overall, if you want something that darkens pages for browsing at night, it's great. However, the toggle feature doesn't really work, the darkener is always one. And it breaks the in-browser PDF reader. It would be better if it at least worked alongside the Dark Mode display settings provided by the OS.

Simply stated, I had to disable it on every web page because suddenly, every website displayed black text on black background, which was useless.I know the problem will quickly be fixed as this is a Ventura issue, and while Ventura is about to ship, it is still Beta software.

loading a page will sometimes result in it flashing from dark to default colors so watch out for that.
