*Lets you make your own colour scheme*

*Can't actually save all the colours without some being changed*

What's the point of letting you "choose" your own colours if the only option is to then "merge" your custom theme with the default colour scheme closest to yours, which causes some of your colour choices to change? Terrible design.

Absolutely best of its kind. It's so great that respectable dev could think beyond some static color profiles and make their work extendable by users. Thank you for your great effort.

Best dark mode and global theme styling addon out there. I think of it as the next evolution to User Styles.

Tip: disable "global sync"

(nevermind, found the corresponding issue on the github --
Yes, it is possible. Just open 'Global settings' tab and uncheck 'Run on all websites by default'.)
Would be nice if you could make it either blacklist or whitelist so I could leave it turned on but it only works on sites i whitelist instead of working on everything except sites i blacklist. *shrug*

Extensão muito boa tanto para o Firefox de Desktop e que pode ser instalada no Firefox Nightly para Android, funciona bem as funções de cores, mas precisa melhorar a resolução de tela da mesma quando executada no telefone.

This add-on is glorious, it is everything I ever wanted and helps keep my eyes in good shape!

super

This extension has allowed me to get the exact high contrast look I want for websites, seemingly not available from any existing themes - at least nothing I've been able to find. For that I give it full marks. Unfortunately I have to lower my rating because it slows down Firefox to such an extent that I had to disable it again.

Makes YouTube look like complete shit. Makes other websites look like they're from 2003. It's hard to make apps like this look good on all websites, so the majority end up looking awful.
