I'm so happy they make this extension. It's an eye-saver and it works really well from what I've seen so far.

Lent.

I can't live without this plug-in. It darkens every single page and it detects if some pages have a dark mode as option (regardless often Dark Reader does a better job).

I was just about to give up on Firefox when I discovered it was this add-on that basically maxed my CPU usage and rendered browsing impossible, let alone multi-tasking.

works like a charm; love the schedule function

コントラストも設定されていて使いやすいです。

Works like a charm and the dark theme is of the right contrast
