I like simple themes so I'd use this one.

Categorized as a Thunderbird theme. Click the "Add to Thunderbird" button and it says "Only for Firefox". Mozilla is somewhat confused. I suppose the theme is okay.

Not a real rating, I've never seen it.

Super znovuzrození.

clear and simple

Themes that are too dark or too light often make the tabs and buttons illegible. This one makes them clearer.

The best simple theme for my bugy miui

Clean, fresh, and easy on the eyes. Awesome.

简洁大方

Good to see details and also for eyes...
