This is a guest post by Mark Subel.

It’s that time of year where the ghosts and goblins come out and we get ready for Halloween night. Kids are making last minute changes to their costume and parents haven’t yet figured out what they’re wearing to the Halloween party. Whatever the case, you won’t run out of options for dressing up your browser this Halloween season. Firefox, IE and Chrome users have a wealth of options for decorating their browsers this year with several amazing Halloween themes available online. Here are our favorite Halloween themes for your browser:

Firefox

Animated Lightning Theme

This creepy theme found in the Firefox personas gallery showcases a spooky haunted house with streaks of animated lightning bolts lighting up the sky. The imagery in this theme is just amazing with a dark sky and full moon to further accentuate the Halloween theme.

Halloween Watching Hour – Animated

Another theme in the Firefox Personas gallery, this Halloween theme displays brilliant imagery of Halloween with black cats, haunted houses, bats, a full moon and cemetery. This theme is animated and you’ll see lights flickering on and off in the house, bats flying and a surprise from a spider right in your browser. We’ll let you try it out to see where the spider appears.

Hello Kitty Halloween Theme

Not all Halloween themes have to be scary. This Hello Kitty theme features your favorite characters in a beautifully designed Halloween scene with happy pumpkins, a bright orange and yellow background, and your favorite Halloween characters like bats, spiders, and witches.

Firefox and Internet Explorer

Halloween 2011 Interactive Personas

This unique Halloween theme developed by Brand Thunder, features Jack-o-Lanterns dipped in a fiery orange molten substance, black and orange background and “Trick or Treat” imagery. Perfect for Halloween lovers. Taking it a step further, this theme is “interactive”, as it provides quick links to Halloween costume websites, Halloween safety tips and a video sidebar showing the spookiest Halloween related videos.

Please note: Brand Thunder themes come with a WebSearch+ toolbar.

Google Chrome

Happy Halloween Chrome Theme

Chrome users will enjoy this “Happy Halloween” theme made specifically for them. A beautifully designed pumpkin graphic with a dark black background and “Happy Halloween” saying displayed underneath. The tabs and bookmarks tab are tinted with light and dark orange to complete this slick theme.

Reader Worlder Mon created this clean, monochrome home screen using a few simple text widgets and a unique icon set.

Flickr user ers_21 apparently longs for a Parisian vacation, or to sit on the streets of Paris and eat pastries and sip espresso, and his desktop takes us there with him. It's clean, monochrome and minimal without being boring, and is still simple enough to not be distracting when it's time to get some work done. More »

If you prefer Firefox functionality but want Google Chrome look, then here is something for you.

FXChrome is a simple, Google Chrome like theme for Firefox 4.

There is not much left to say other than: click here and check it out.

Be sure to check the installation instructions.

Customizing our computers is a cool way to personalize the machine we work on. Working on a computer that we have personalized and are comfortable with increases our productivity. There are various methods in which you can customize your computer; one of these methods is to customize the look of your favorite web browser.

Personally, I prefer Google Chrome over all other web browsers. I like the quick response time and security it offers. The browser also offers a gallery of themes that can be used to customize its look. But instead of selecting something from a list, I like to create my own themes.

Below you will find the tools that I use to create my browser themes for Google Chrome. I hope they will help you personalize your Chrome experience as they helped me.

1. ChromeThemeMaker

ChromeThemeMaker is the first entry in my list because it is the easiest one to use. The application is basically an online tool. It lets you modify numerous factors that contribute to the look of Google Chrome. You can edit the frame, toolbar, tab, and background of your Chrome window.

You can select from a list of available options for each modifiable control.

Alternatively you can upload your own options to give your theme a truly personal touch. The site provides some samples for inspiration.

When you are done editing your theme, you can either download it or directly apply it to your Chrome.

ChromeThemeMaker can be visited here.

2. CRX Theme Creator

CRX Theme Creator is a freeware application for Windows operating systems. The slight delay in response time experienced in ChromeThemeMaker is absent in CRX because it is a desktop application. The app comes as an EXE download sized at 256 KB. To run CRX you simply double-click its EXE file – no installation is required. This is what the programs looks like when running.

Through a single window you are able to control almost all aspects of Chrome’s look. To name a few, you can set colors for the toolbar, bookmark text, and the browser’s frame.

You can also set images for the tab background, frame, and toolbar.

After completing your modifications you can name your theme and create it to be loaded to Chrome or shared on ChromeTheme.net.

The “CRX Theme Creator” can be gotten from here.

3. Chromium Theme Builder

Chromium Theme Builder is another desktop application for creating Google Chrome themes. This one has comes as a ZIP archive sized at 816 KB. You have to decompress the archive and run the extracted EXE file to run the program. Just like CRX, Chromium Theme Builder does not require an installation. This is how the program looks like while running.

Usage of the application is very simple. A mini-view of Google Chrome is presented in the app’s interface. You click on the Chrome element that you wish to modify. Doing so will open the images folder of that element. All you have to do is edit the PNG images contained within this folder.

Repeating this step for all Chrome elements will give you a fully customized Google Chrome theme that you can later build and test using the application.

Ever since Chrome's theme gallery launched, we've seen a steady flow of awesome themes.

The Gmail team has just announced five new themes for Gmail:

• Basic Black: Shown above, it's a bare bones high-contrast theme; it's actually quite soothing.
• Basic White: It's the same as Basic Black, only in white.
• Android: This one seems like kind of a shameless marketing move (where's the "iPhone" theme?), but it's really a nice theme. You get a subtle circuit-board pattern up top, with a tiny Android hanging off of the Chat pane. It's very reminiscent of the Android theme for Google Chrome.
• Tree Tops: It's exactly what it sounds like. You get a bunch of foliage in the header, and the whole thing is very green. It's not particularly exciting.
• Marker: This theme takes a highlighter to Gmail. It basically makes it look as if the Chat window and various headers are just "markered in" by hand. This one is actually the coolest - I think I'll be keeping it.

The themes are already available for both Gmail and Google Apps users. Try them out, and if you can't decide you can always just click Random at the bottom right corner!

So, you want to change the look of Google Chrome, but you're not happy with the options available in the official Themes Gallery? Well, I've got good news for you: there are plenty of good themes available elsewhere.

In fact, there are loads of themes in the Google Chrome Extensions Gallery. Wait, what? Yes, I know -- a theme is not an extension. Sure, they're the same file type (.CRX), but that's pretty much where the similarities end. Still, the Extensions Gallery is the only official place that designers can upload themes right now; hopefully, Google will add a "user created" tab to the Themes Gallery someday.

There are other sites where you can find themes as well -- deviantART and ChromeThemes.org, for example. Take the jump and have a look at a few of the better ones I've found. Taste is subjective, of course, so feel free to link your own favorites in the comments!

Robot Theme
Normally, a single theme doesn't warrant its own post, but Robot Theme was just too cool not to share. It remains one of the most popular Google Chrome themes in the Gallery.

Foxy Theme
Drawing inspiration from the Firefox 4 UI, Foxy is the perfect theme for those of you who love your Aero transparency. It's difficult to notice the effect on inactive tabs if you have your Chrome window maximized, though.

The Simpsons Theme
MMmmmm ... yellow. Yes, it's loud, and it might not be your favorite color, but you've got to love the disgruntled Homer in the corner of the new tab page.

BioShock 2
The fan page at Bioshock2.org actually has two themes available for download, and they're both super-grungy and dark, which is pretty much exactly what you'd expect for a Bioshock theme. You can also find a couple more over at deviantART.

XP Royale Blue and Zune Themes
If you're still running XP, chances are good that you're using one of the nice Royale themes. StudioJanck's Zune (black) and Royale Blue themes are nicely done and match the updated, glossy XP look.

Muku
Yes, there are people out there who like wood themes, and Muku is a nice one for Chrome.

Elegante
Chrome themes don't have to be complicated to be good; there's not really a heck of a lot to see, after all. Elegante imparts a nice, simple grayscale look.

Green Day: Warning
I'm not sure what it is about the green-on-stone gray look in this theme, but I like it. If you're not a Green Day fan but still like the look, just throw in a new tab extension like Incredible Start Page to replace the default. (note: if you're not a fan of SendSpace, download this theme from here.)

Nightmare Before Christmas and Alice In Wonderland
If you're a fan of Tim Burton's animated classic or his more recent Alice remake, these two are definitely worth a look.

Runescape
I'm not a RuneScape player, but I actually kinda like this theme. It's well done, and it's readable, which is one important characteristic that a lot of themes seem to forget about.

If you're running Google Chrome on Linux, switching to the "dev" channel seems like a smarter bet than ever. The newest release includes support for desktop notifications (as previously suggested), and better integrates with your GTK/GNOME theme by using its text and button selection colors. Plug-ins, too, can now be stashed in a location in your home folder for backup and maintenance.

Earlier this week, I read an interesting article in the New York Times about shokunin kishitsu, or the 'craftsman's spirit.' The craftsman's spirit in Japanese culture basically appeals to all of us, regardless of vocation, to aspire to beauty in everything we do and create.
