Phoenity Shredder

If you're looking to spruce up your buttons in Thunderbird, the Phoenity Shredder extension is a great option. It adds warm and sunny tones to your buttons, enhancing the appearance of the overall interface. That being said, it's important to keep in mind that Thunderbird 3 (also known as Shredder) is still in the alpha or beta stage, meaning that it's a moving target. This means that not all new or changed features will look good right away, so be prepared to make some adjustments as necessary.

But despite these potential challenges, Phoenity Shredder is a cross-platform extension, meaning that it works seamlessly on Mac OS X, Windows, and Linux. So, no matter what type of computer or operating system you use, you can enjoy the benefits of this stylish and functional Thunderbird extension.
