This is one of the few dark Firefox themes I could see myself using on a regular basis.

BlackFox is a very nice looking dark theme, with just a hint of red to help highlight your selected browser elements.  The entire them has been designed to be focused, compact, and easy on the eyes.

The theme’s author also promises that it is compatible with a long list of popular extensions too.

You can pick up BlackFox via the Firefox Add-ons web site or check out the theme’s official web site, at zigboom.com.

Very clean and easy on the eyes, two things you can say about the ArzoFox theme for Firefox.  I like themes that can make the browser experience better just by touching up a few things.  The gradient background, mixed with the colorful icons is a great combination that is really hard to beat.

Like what you see?  You can pick up the ArzoFox theme on the Firefox Add-ons web site.

If your looking for a mostly 2D, grayscale and compact theme for your Firefox browsing ways – look no further than the Two Dimensions theme.  As you can see with the screenshot I included, it is a very slick skin for your Firefox browsing ways that will not disappoint those of you who like to keep things simple. 

It would fit nicely, I think, in my list of lightest popular themes for Firefox.  Who knows, it might earn its spot soon enough.

Thus far a five-star theme, that is rising in the ranks, you can pick up Two Dimensions and add it to your own Firefox installation at the Firefox Add-ons web site.

Here is a little more about the themes in question from the developer:

What basically started as a small project to simplify and shrink the default Strata Theme has turned into a distinct theme. The icons are designed around the simplified Stop, Reload, Back and Forward icons of Strata… expanding those basic elements across the entire interface.

You can now download either or both!  Be sure to let me know which one you decided to use and why. 

Stratini

Stratini Padded

I really enjoy the themes that can keep it simple, yet give me something new and fresh to look at that doesn’t look like it was ripped from the theme down the street.  Both Stratini and Stratini Padded pass those test, so they get two enthusiastic thumbs up from this Firefox fan.

The GMail Compactor user script will help you reclaim that space with style.

As you can see, from the picture above, after you install this Greasemonkey user script, everything from your Compose Mail link down to your Contacts link are now minimized into very pretty icons.  As an extra benefit, you also still get the count of how many new messages are in some of your folders, such as Spam.  If you want to maximize the vertical real estate in Gmail, then pick up the Gmail Compactor user script.  (found via Lifehacker)

The major benefits Compact Menu 2 has over Tiny Menu are:

• An even smaller footprint (one small blue globe to access your regular menu bar items)
• You can move it anywhere (Tiny Menu was locked to one location)

As far as customization goes, you can select the menus you want to see in the new popup  compact menu.  These are:  File, Edit, View, History, Bookmarks, Tools, Help.  Each has a check mark beside it, so if you don’t want to see it – get rid of the check mark, and then save your settings.

One thing that might catch people off guard, is it doesn’t work right off the bat after you have installed it.  After installation, right-click on menu bar and choose “Customize…”, drag the “Menu” button or the “Compact Menu” icon to the position where you like on toolbar, then click Done.

Compact Menu 2 has earned it’s spot into my day to day use, so I give it two thumbs up.

As said by the author of this awesome theme, a lot of love has been put into it, so that it looks great in any windows theme.  If you want to pick it up, you can grab it on the Firefox Add-ons site or visit the official hmmXP theme site to get the latest version.

Sometimes keeping things a little more compact means that you have more room for the more important things.

That is where the Classic Compact Firefox theme is so valuable. It gives you that classic look of the Firefox theme but in miniature form.

A very compact version of Firefox’s default theme, which minimizes vertical space consumed by menu, tool, tab, find and status bars as much as possible without hurting overall appearance.
