Here is a little more about the theme from the developer:

"BFT EVO", born from my first theme Bloomind FT Graphite "ashes", is a theme that has been created to fully transform the look of Firefox for Windows users. As all the Bloomind theme serie it contains no added functionalities and it has been especially designed for Seven, but rendering is relatively accurate on XP and Linux (I don t own a MAC so I can t test my theme on this platform to check if rendering is ok, but according to few MAC users who tried my different works, Bloomind themes seem to be MAC friendly too :) So if MAC users would like to try any Bloomind theme, they can force download and drag the file into the addons manager page to install it).

Want to take a closer look? Here is how it looks when you are diving deep into the Firefox button’s menus. 

You can pick up the BFT Evo theme for Firefox at the Firefox Add-ons website.

Bloomind FT DeepDark 2 really transforms the look of Firefox 4+ for Windows users.  It has been tested to work though on both Windows and Linux with little to no issues.  The entire theme is very sleek looking.  I hope to see more Firefox themes like it in the future that pay attention to detail and get every inch of the browser themed over like Bloomind FT DeepDark 2 does.

When push comes to shove this is a clean theme with cool colors.  You can pick Bloomind FT DeepDark 2 up from the Firefox Add-ons website.  If you’d like to see it in a different color, you might also browse through some of the other variations that have been released.

Who bleached my Firefox? If you are going for a minimal and clean interface, you can do no better than the Simple White theme for Firefox.  This extremely all white theme of Firefox might sound a like a ‘bit of an oddity at first – but once you use it for a while, you will really appreciate the simplicity of it all.

This theme brings a whole new meaning to the phrase, "having a clean interface". Several more features have been added to this theme, other than just turning the theme white:

• Width of tabs has been reduced
• Unselected tabs are semitransparent (when Aero is turned on)
• Better compatibility with Windows XP

If you want a way to de-clutter your desktop, then going with this minimal, modern and simple theme might be the best way to start.

The Simple White theme has been tested to work on Windows 7, XP and Ubuntu 10.10. You can download the Simple White theme for Firefox from the Firefox Add-ons website or the official Simple White website.

Here is a little more about the theme from the designer:

This skin makes Firefox 4 look like Firefox 1.5. Remember the cute skin it was… simply amazing. With this skin, the interface, the tabs, and the download manager were reskinned to look like Firefox 1.5. Useless stuff cluttering the address bar, like the Bookmarks star, the RSS icon and the Go Button have been removed in order to simplify the interface. The ugly green security bar has also been removed.

Personally I think some of the spacing and padding seems to be a ‘bit off, so I can’t use this as my everyday Firefox theme, however I do wish them the best of luck with keeping the old Firefox 1.5 theme alive.

Want to give it a shot? Just head on over to the Firefox Add-ons website to download it or visit realfox.net.

Here is a quick screen grab of my own Firefox installation using the old Firefox 3 icons:

I do have to say, I don’t mind the change.  All of the design aspects from Firefox 3 that they decided to keep feel like they fit right in with Firefox 4.  I think I might actually use this theme for a while.

You can pick up the Firefox 3 theme for Firefox 4+ over at the Firefox Add-ons website.

The ACE Foxdie theme for Firefox might very well be one of the most creative themes I have seen out there today for the Firefox browser.  Now, that is pretty big praise to give any theme out there for Firefox – but let me tell you why I think this is so.

Once you install this theme for Firefox, you are actually given options on how you want the basic theme to look and feel.  You choose how the buttons look, the appearance of the browser, how it integrates with the rest of your operating system, and you can enable or disable a handful of tweaks.

• Under the Buttons menu, you select the size, color, shape and texture for the Firefox browser buttons.
• Under the Appearance menu, you choose how you want the tabs to show up.
• Under the Miscellaneous menu, you can hide favicons, change the location bar, and tweak with other browser settings.
• Under the OS Integration menu, you have the choice to choose what font you want to use, or to disable text-shadows in certain places.

You can tell a lot of love went into making this theme fantastic.  Just within this one theme, you have hundreds of different customization options, and nobody’s browsing experience has to be the same.

You can pick up this great theme from the Firefox Add-ons website.

Want to make Firefox look a little more like Facebook?  I have a Firefox theme for you that takes its inspiration from the social networking juggernaut.  The Facebook theme for Firefox actually does a pretty good job at giving you a Facebook looking browser – but still seems unique enough to not be called a carbon copy.

You can pick up the Facebook theme for Firefox from the Firefox Add-ons website. To learn more about the theme author, be sure to check out thechillroom.com.

Looking for a darker Firefox theme, that has some aspects of the new Firefox 4.0 look built inside?  If so, check out NightShade.  This slick dark theme is almost a perfect representation of how a great dark theme should look.

In the creator’s own words – this theme came about to be an updated version of the popular RulerDark theme.  So if you have seen it before, this is probably where you saw it last.  However, it appears the creator of RulerDark stopped updating it – so the new creator found a perfect place to step in and take over a great looking Firefox theme.

To learn more about the development of NightShade, be sure to check out the official website. To download the theme and use it to decorate your browser, head on over to the Firefox Add-ons website.

Sometimes, finding a good Firefox theme is hard to do.  Thankfully though there are still themes out there like Qute that look great, are lightweight and don’t kick you in the face with a stylistic nightmare of clashing colors.

As one of the oldest themes for Firefox, that is still updated, you have to give credit where credit is due.  The reason this theme has lasted since before Firefox 1.0 is clear.   They keep the interface clear of clutter, the icons are polished, and it does not stray too far from the default Firefox style we are accustom to.

You can download the Qute theme for Firefox from the Firefox Add-ons web site. Go revisit one of the oldest, and maybe the best, alternative skins out there for Firefox.

Feeling a little iBlu today?

This is a great unique theme I have been keeping my eye on for some time now.  Gradient iBlu gives you a nice and simple black interface to work from with gradient colored blue icons, that stand out from the rest of the pack.

Does this theme look a little familiar to you?  Well, if you find yourself thinking that, you might go back and check out my review of Gradient iCool.  It has the same great interface and button setup, but has shinny buttons instead.

Go visit the Gradient Studio to learn more about this great theme (and many others) or go pick up Gradient iBlu at the Firefox Add-ons web site.
