If you are looking for the best dark theme to decorate your Firefox browser with, take a look at Bloomind FT DeepDark 2. While the name does not roll off the tongue, it is the most downloaded Firefox theme at the moment via the Firefox Add-ons website.
Great Dark Theme for Firefox
Combine Search and Address Boxes
For all the things that the most recent versions of Firefox have done for simplifying the interface, why do we still need to have a separate box for searches? If you are like me and are needing a way to simplify the browser even more – try out Instantfox.
White and Bright Firefox Theme

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.
Take Firefox 4 Back to 1.5′s Theme
While someday we may look back at the Firefox 4 layout and miss it too – some people out there are still missing the good ol’ Firefox 1.5 theme and layout for Firefox. If you want to recapture the magic of when you probably first tried the revolutionary Firefox web browser – then check out Winestripe Realfox 4.
Chrome Up Firefox 4
Firefox 4 really brought a new look and feel to the browser that was refreshing for me. However, some people still like the overall look and feel of the Google Chrome browser more. Well, now you can have the best of both worlds with the FXChrome theme for Firefox.
Image Tools for Firefox

Looking for more options and tools when it comes to viewing pictures from within Firefox? The very obviously named Image Tools add-on for Firefox will give you a few more basic controls when it comes to viewing images from within the browser.
Bring Graphite Glow to Firefox

The world of Firefox 3.6 themes is really slim pickings these days. Well, there still are a lot of great themes, however most of them I have already covered here more than a few times. However, I am happy to say I was surprised to find this suggestion in my inbox this morning. Bloomind FT Graphite really transforms the way Firefox looks for Windows users.
MonoChrome Firefox

Like the default Firefox theme, but find it to be a little too colorful for its own good? Then you might want to check out the Firefox theme – MonoChrome. It brings Firefox back to basics with everything turned black and white and grey all over.
Add Polish to Firefox’s Strata Theme

With all the buzz surrounding the Firefox 4 redesign making us excited for the next best thing, I have to remind you that there are still some great themes for our current navigation and toolbar layout too. Strata Reloaded gives the basic Windows Firefox theme a fresh overhaul, and makes it look even nicer than before.
Improve Readability

In a day where we have fantastic website designs, terrific layouts and tons of stuff to check out on the web – we sometimes forget that some people have more readability problems than most. The Readability add-on for Firefox looks to change that. It strips all the fluff from the webpage you are looking at – and delivers pure content.
