works on windows 7, or windows 8/10 with a css

Really awesome. I love win7 transparent windows, with this theme I can apply it to firefox as well. Love it!

This is awesome.Thank you!

Sometimes I don't want a color or background, so this is great.

非常用心，其它主题只有标签页透明，同时标签页上的字却看不清了。这个主题关注到了这个细节，并且做的很好。

今まで色々なテーマを使ってみましたけど、これが最も素晴らしいデザインだと感じました。

Best themes.Respect developers you are the work

I was looking for matching theme for my browser. And in this case, it's perfect. Love it!

Only Transparent theme i have found in Store and really a great work.

good transparency ... well done .

it's best theme i'd ever found

Dá um novo ar ao Firefox! Bem que poderia ser um tema padrão dele.

I am using a dark transparent windows theme and this is just perfect to go with it. Thanks a lot!

Transparency that works well with dark desktop (uxstyle) themes as it has white text. Also seems to be more often successful at applying to my lower (below-window) toolbars than many of the other themes.

Maybe the best theme on firefox.

Красиво, то, что искал!

is beautiful with aero of windows!

It looks beautiful with my aero glass desktop. Aero is the main reason I haven't moved to Windows 8.

This is so perfect. Why it isn't in the top 100?!

My prayers were answered! Finally I CAN have my OWN (Windows8) color scheme using this awesome theme! It's not just another "me-me-me theme, but one that allows others to be a little creative with the little technical knowledge they have - like myself :) Thanks a million!

Thank you very much! You replaced the old theme that I was using which hadn't been updated since 2012.

I didn't care for the look of the only slightly transparent grey tab bar in Firefox 29. This makes it look extremely similar to all of my other windows in Windows 7 with Aero Glass. Thank you very much, I love it! Also, it is very easy to see the tabs and address bar features even with the transparency.
