Very good, very nice!

simple and elegent

I like it. I was having serious trouble with the new Quantum as it is very high contrast, bright whites along intense blacks, and found this simple, soft theme that has made all the difference. Thanks for saving me Andrew!

This is exactly what I was looking for. A neutral gray theme that makes the browser interface readable and legible without distracting from web pages. Andrew, thank you for creating the theme that should be the default Firefox theme.

After redesign of Firefox tabbar this is the best solution to return readability to favicons, they were just invisible on black background. Thanx for this clean and native-looking theme!

После редизайна Файрфокса - это лучшее решение, чтобы вернуть читабельность иконкам в панели вкладок, которые на чёрном фоне стали неразличимы. Спасибо автору за чистую и гармонично выглядящую тему!

Nice and simple. Thank you. Mozilla, take a leaf out of his of her book and return to you roots : a fast no nonsense browser.

Great with FireFox's new look

The flat look is very nice on OS X 10.10 Yosemite.

Very nice and legible, without background images or distracting colors, so you can focus on the page content, not browser controls.
