I've been using this add-on/extension for around 2 years now, and one of the reasons for me still using it right now would be the fact that it is easy to use while fully customizable. I really do think that any and everyone should try this one out because it can be very useful, I say this because it is automatically applied to sites and you can toggle them on and off when you get to any sites as you please...

Amazing addon

Muy buena

Best addon to set colors in browser pages. I have visual impairment and cant read pages that are white background. Too bad devs dont remember to allow changing to DARK MODE... This addon allow us to se background to any color we like... And change font color, link color, visited link, etc...
A melhor coisa para quem tem problemas visuais... Tive catarata e nao consigo ver paginas com o fundo branco... Muitos programadores se esquecem que existem pessoas com problemas para ver paginas que nao possuem a opcao de MODO DARK... Com esta extensao nao tem este problema... Basta ajustar a cor de fundo, da fonte, dos links, etc... E ja era o problema... RECOMENDO MUITO...

I love you. <3

Finally a dark style extension that works for most pages. Enable only for specific pages or for all pages. Not many styles that doesn't work properly and confuse you but a few good ones. I like it a lot.
