Awesome!
This is exactly how I want my Thunderbird to look.
I even have the placebo feeling that Thunderbird is faster!

Yah, I just wanted my Thunderbird to look like it used to before I upgraded. This is much closer to the way I want Thunderbird to look.

Completely strips the grid from the calendar making it very difficult to read. You will also lose your quick open icons in the tab bar.

Apart from that, tabs are difficult to see. I can't even tell which is the active tab.

"Mostly Crystal" theme is similar in feel (though the icons aren't quite as "retro") and just plain works better IMHO. There are reasons after all, that designers have changed the way things look over the years...

Wonderful classic theme here, mission accomplished! No nonsense, utilitarian, and to the point.

Capturing an "old fashioned" feel was obviously the developer's entire goal for this theme. It's brainless reviews like yours that screw up the entire rating system. Would you go see a country music group perform and then complain about how it doesn't even compare to an opera?

Use your brain before hitting that review button next time. There are enough mouth-breathing neanderthals around here as it is. We don't need another review-troll with an intelligence-level that is right on par with a boot full of hair.

I love this theme. Can't wait for the version that works with Thunderbird 3 to come out.

You did a fantastic job! It is great that you made both Thunderbird and Firefox themes. They are a nice couple again! I work with a simple and clean interface that give me a fuzzy nostalgic feeling, but at the same time I know I work with totally accurate and up-to-date software.
I feel sad for the Apple users though. It would be perfect if they could enjoy all of this beauty to.

Thank you for your feedback. Is it not possible to use the Linux version for Mac Thunderbird? I have heard of people using the Linux version of Orthodox for Firefox on Mac OS and it seemed to work.
