It would be nice if you could change only one thing and leave the rest default, like changing only the text color, but changing the text color means that the background and link colors will also be changed like it or not, and that makes this extension useless to me.

Looks like the extension I need, but the control panel only lets me change text color and background color. There's at least a third setting, possibly more below those two, but it's mostly off the control panel and can't be brought into the control panel. I find no way to contact the developer, so I'll post this.

This is listed as an add on for firefox for android.

Doesnt work as promised. No customization for web site colors. click to change colors on any site just applies a generic samey (and while at least dark not very pleasing to look at) theme to any of them. bad addon. do not recommend this at all. better to just stick with stylish like all these years before and pray theres pretty and up to date custpmizations up on userstyles.org (or write one yourself)
