It has only been several weeks since Google+ opened its door to limited users and it has already created plenty of buzz. While many people still have not gotten their invites, there are already 10 million users on the platform and a billion items shared per day. If you find yourself terribly addicted to Google+, Here are 15 Google Chrome extensions that make using Google+ a better experience.

1. Google+ Ultimate

Is the Google+ design too bland for your taste? You can now customize the color and style of Google+ with Googlt+ Ultimate. Things that you can customize include the background, scrollbars, left and top panel, navigation bar, image size in stream, side-by-side view (for large monitor).

2. GTools+

GTools+ is developed by the same developer as Google+ Ultimate. It acts as a complement to Google+ Ultimate and allows you to customize the Google bar as well as integrating the chat feature to the Google bar.

Chrome: Smooth Gestures is an add-on for Chrome that allows you to open new tabs, close old tabs, reload pages, and open links all using mouse or trackpad gestures you configure and toggle with hotkeys. More »

Chrome: Buffer is a webapp that will schedule and publish articles and links that you want to share with friends on Twitter on a schedule that doesn't annoy your followers and make them want to unfollow you.More »

Have you ever wondered what the Web was like before the Mosaic Web browser? If you were born in the last 20-odd years, or you only discovered your inner geek recently, did you miss out on monochrome monitors and the dial-up BBS era? Well, here's your chance to get a sneak peek at history: grab the ChromeLite extension and marvel as the entire Web is transformed into ASCII characters.

Now, ChromeLite isn't actually all that functional. For the most part, it simply strips images and converts text into a monospaced terminal font. There are a few Easter eggs inserted -- such as a fun message at the bottom of YouTube (image after the break) -- and some fun ASCII art, but that's about it. Rather oddly, most JavaScript continues to work -- so you can still enjoy Google Instant Search!

ChromeLite was actually made by Google as an April Fools' joke -- and indeed, an annoying 'you can uninstall this!' message appears at the top of every page -- but we're kind of hoping that Google, or another developer, takes ChromeLite and turns it into a real ASCII browsing extension with configurable settings. If anything, it will provide an easy way to save bandwidth and CPU time.

Wikipedia Beautifier is an extension for Google Chrome that removes all the clutter from Wikipedia and lets you focus on the most important aspect of the online encyclopedia: its content. Wikipedia Beautifier has been inspired by Readability, and aims to provide the same amount of article-centered beauty, while also keeping the familiar navigation menus within reach.

Now that Google Chrome 11 has hit the beta channel, you can expect to see extension and Web app developers making use of the new HTML5 speech-to-text API. In fact, there's as least one slick extension you can already install: Speechify.

Install Speechify, and you'll see a microphone icon added into the search box on many popular sites -- like Google and Bing. Click it, and Speechify will convert the words you speak into text. You've still got to press enter or click to search, and an automatic submit option is definitely something we'd like to see added.

Hundreds of millions of people are now using Google Chrome as their primary Web browser, and a good chunk of those users have probably checked out extensions or Chrome Web apps by now. If you've ever wanted to share your favorites someplace -- like Twitter, Buzz, a favorite forum site, or even via your Gmail account -- there's a new extension out that makes the process dead simple.

Winning points for clarity with the name Share Extensions, the add-in will automatically create BBCode, HTML, Text, and Wiki markup detailing your chosen extensions. Each extension's Chrome Web Store URL is included, as is its name, and you can optionally include the developer's description as well.

I did have an issue sharing via Gmail when selecting several extensions at once, but the pop-up text generator worked just fine every time. Share Extensions also adds a browser action icon, but you can always right click to hide it or resize the action area and slide its icon behind the double-right arrows.

If you're a social networking butterfly, or if you have the malevolent aspirations of one day becoming a 'social media expert,' you almost certainly spend a vast amount of time surfing the Web. You probably use a modern browser like Firefox or Chrome, and you almost certainly have a ton of tabs open at the same time.

It can be hard work, keeping track of multiple websites. Hitting F5 is a pain in the ass -- and waiting those few seconds for a page to reload can be mighty frustrating. Then there's the matter of remembering all of your login names and passwords (because you don't use the same password on more than one site, right?)

Wouldn't it be great if there were some add-ons and extensions that could make light work of your surprisingly busy social networking lifestyle? Even if you only use Facebook or Twitter, there are still plenty of annoyances that could be offloaded to add-ons.

The open and free alternative to the Chrome-specific Web Store is now almost upon us! Developers, feast your eyes on the first milestone release of Mozilla's Web Application project.

Developers, this milestone release means that the OWA Application Manifest spec is now stable -- so you can now safely begin building apps. There is also a stable JavaScript API that you can use to interact with the browser (installing, uninstalling, etc.) There's also the beginnings of a tutorial that you can use to get started.

It might only be a couple of years old and its extension interface might not be quite as powerful as Firefox's, but in terms of developers, big-name publishers, and sheer numbers, Chrome already has a very healthy ecosystem of add-ons.

When you factor in Chrome's exclusive selection of Web apps, it's even possible to say that Chrome has a wider variety of extensions -- or at least until Mozilla launches its Open Web Apps later in the year.

Still, as always, the problem with add-ons is finding the right ones. You have thousands of add-ons to choose from, and only a handful that are actually worth using. First-time users haven't got a snowball's chance -- unless they read this list of must-have extensions!

But this list of extensions is for converts, too. With massive defections from Internet Explorer and Firefox, Chrome has grown from just a few million users in 2009 to over 120 million at the start of 2011. Firefox users will be especially pleased to find almost every add-on has a comparable extension -- and IE users... well, they'll just be glad to have any extensions at all.

Whether you are looking for helpers or shortcuts, or full-blown Web apps, you will be pleasantly surprised with the variety and power of Chrome's extensions.

CueThat is a slick little browser add-on that lets you add any movie you happen upon while browsing the Web to your Netflix queue. Just highlight a title, right click and choose CueThat from your context menu, and voila: it's added to your list. It even works with movies that are still only screening in theaters.

CueThat is offered as an extension for both Firefox and Chrome, though the bookmarklet works just as well and is usable in any Web browser. It's well worth adding to your bookmark toolbar if you're a Netflix user who hunts for movie reviews or recommendations while browsing the Web.

One of the oldest -- yet somehow least-lauded projects in existence -- is Mycroft. Perhaps its under-hypedness is due to its total simplicity -- Mycroft is nothing more than a massive directory of search plug-ins that you can add to Firefox, Chrome and Internet Explorer. Check the top 100, and you'll get some idea of Mycroft's scale.

For Firefox and Internet Explorer, this means you can search just about every site in existence from the Search bar in the top right corner of your browser. For Chrome users, this means you get even more functionality from the uber Omnibar.

Incidentally, Chrome users, did you know that you could use specific search engines from the Omnibar? When you grab a search plug-in, make sure you provide a keyword. Make it something short -- like 'pb' for Pirate Bay or 'imdb' for IMDb -- and then, when you want to search The Pirate bay, just type pb, followed by your search term.

Google has already announced that it would be dropping H.264 support from Chrome, but some other key players in the browser arena aren't backing down. Microsoft, of course, is standing behind MPEG-LA's codec -- and now it's making sure that Chrome users will still be able to view HTML5 video embeds which are encoded with it. The magic will be handled by a new browser add-on called Windows Media Player Extension for HTML5. No, it's not a full-on plug-in -- which is kind of what we were expecting, given Microsoft's affinity for NPAPI tomfoolery.

To add the extension to your Google Chrome install, just visit Microsoft's download page and agree to the alert you see above.
