Very simple but it's perfect, thanks

ooh!

I agree with user Chris, below, one star only because of the flash of white.

Also, to "Firefox user 4981570" who suggests updating/creating userchrome.css, your suggestion doesn't remove the white flash.

And, finally, to "Developer response" below, your suggestion doesn't work on Firefox for Android. Did you forget that this browser runs on multiple platforms, not just the one you work on?

In summary, total garbage. As per.

Created a firefox account just to leave this review. I initially installed black new tab and the first time I opened a new tab I got an ad in the lower right corner and assumed it had to do with the app, so I left scathing feedback when I uninstalled it. I have since seen this ad again and now realize it was just an unfortunate coincidence and that the ad was just something firefox did that I needed to disable. Apologies for my harsh words if they reached you. Anyway, I love this app! The perfect companion to Night Eye.

This extension is just straight up epic.

Very good! Works great for new TABS, but new WINDOWS are still glaringly white. Fix that for the full 5 stars! :-)

about:blank but this time in black!

Works as expected, I only wish there were still a button/area to click to open regular about:newtab

How can the people that code Firefox not have this as a default option by now?

Does exactly what I expected.
downloaded to be consistent with my overall black UI

Tut was es soll. Endlich ein schwarzer augenschonender Screen anstatt das helle weiß! Danke dafür!

there is a delay from white to black

So easy
