I can't believe I haven't looked much earlier for an updated github dark theme with support for different syntax highlighting

https://github.com/StylishThemes/...

That's the one I'm using here too :3 great theme indeed!
One little remark that I have about it though: I hate how small it makes the code field. So I added this little snippet on the bottom:

/* My own witty edits */
.container{
width: 1480px !important;
}

@Condor wouldn't you have to adjust also:

.container-lg {
max-width: 1480px !important;
}

for the top bar and other content?

@JoshBent that's the one I've been headscratching about for a while but my lack of experience with the Chrome devTools couldn't help me with. I'll try to remember to apply that as well 🙂 thanks!

@Condor haha you're welcome

This add-ons, are good with privacy? I access privet github repos, would this be a concern?

@carlosjpc no problem
Just a css swap

@CozyPlanes thanks man!

Stylish was removed from addon stores for a reason: Data collection. Don't use it.

@filthyranter Stylus is a fork of an older version is Stylish before it was sold to an "analysis" company. I believe Stylus is open source.
And it works with Stylish themes

Thanks for the tip :p Love it

@filthyranter as @Charmesal said, the docs/readme exclusively mention stylus too, nobody uses stylish anymore.
