Yep, this is clearly the superior theme. The text is much more readable.

I've also been using this "different GitHub Dark"; I'm not sure which one i prefer - the grey background instead of black is also pleasant for the eye... i'll have to try them both for a while.

Same, Github has way too much white on the page and it absolutely kills my eyes. I've been using this for a few months and there's no way I am going back.

Is this based loosely off JetBrain's style? I notice they said "twilight" which looks/feels awfully similar (which is my favorite).

Thank you very much Michael! Never thought about this, I just wish there was something that could change sites globally.

Deluminate[0] for Chrome does a pretty good job of this. For some sites I find it does better than whatever themes happen to be available on userstyles.org. In other cases, it performs pretty poorly but it's still far better than having to hack together something myself for sites I care about.

I liked this a lot, but it is way too heavy. Almost kills scrolling here, even on super-light sites as HN.

Interesting. I haven't experienced any noticeable performance issues at all. My biggest annoyance with it is that it sometimes make horizontal scrollbars appear when they wouldn't otherwise.

My computer is old.

On mobile, Firefox for Android has an neat addon for that:

Dark Background and Light Text by Mikhail Khvoinitsky https://addons.mozilla.org/en-GB/android/addon/dark-backgrou...

It just works™ about everywhere. It is also available on the desktop version, although I've never tried it myself.

For late night browsing/reading, I use flux's dark room mode, which turns everything into red and black.
