In my book, this is the best darkmode addon in the whole Firefox repository.

Unfortunately it suffers from a massive, deal-breaking flaw: lacking a way to quickly cycle through themes.

Most of the time Dark Mode works great, but often enough the theme renders a website or some element/s of it poorly.

This should be a simple fix because Dark Mode has a variety of internal themes and customizations to offer. However, in order to do that one has to right-click the menu bar button, click "manage", then go into the Dark Mode settings menu, and from there select "preferences", in order to access the customization screen.

It's too many steps already to get there because this is a frequent state of affairs, but that's not all. To find a working theme you have to select a new one, then switch back to the broken page to see what it looks like, sometimes requiring the page to be reloaded, and quite often the new theme is broken too, so you have to go back and select a new one, and so on, back and forth, until you find one that works. The Dark Reader addon, for comparison, changes themes instantly, and directly from the page you're trying to alter.

But even then that's not the end, because Dark Mode runs on a single global theme setting. It doesn't save theme preferences on a per-site basis (again, unlike Dark Reader), so once you've chosen a new theme that you like and that works, odds are that instead you now broke a bunch of other pages.

This makes it completely unusable to me. And it's a great shame, because there is a simple fix- providing a keyboard shortcut to cycle through themes directly from the page (one last time- like Dark Reader does).

If these issues were remedied I would probably swap to Dark Mode permanently.

Just my two stars.
