Update: Tried to use this as this is the one of the only ones that seems to "work" on the mobile Firefox platform. But today I had to uninstall it. The script that this addon keeps crashing and I have to either "stop script" or "continue" when it does crash the page. This addon is absolutely clumsy... Grateful that it is free, but even though it is free, it is unuseable...

OLD:
I really tried to love this extension. After getting a notice that a Dark Mode extension was no longer certified or checked or whatever the mozilla folks are determining safe use was no longer safe, I switched over to this one since it was "recommended" and seems like mozilla was ok with it (whatever the hell that means).

The interface is clumsy, can't you just implement a simple switch?

When you do turn it on or off, you have to refresh the page, which sometimes destroys the content of the page.

I really really tried to like it, not give it one star cause you deserve an extra start for effort, but the quality of this extension is an F. It's clumsy, too many options (just give us dark mode, 99% don't care to tweak the little things, it gets in the way).

Why are "dark mode" so hard to implement? Just flip the white to black, black to white, and if the pages don't come out right, we'll just force it back and complain to the webmaster. I just don't get it.
